    It's been a while so I figured I would update a few of you.

    Now that I had finished up with the engine bay deletes I wanted to get started on the structure foam before I shipped the car out for paint and body work.

    I ordered the foam from Fomo (yes, they bought out ITW Foamseal for those that know something about this product) via Grainger. Grainger now stocks the foam and is a great choice to add to any Z32 for a little bit of extra rigidity at almost no weight additions to the vehicle.

    Here are some of the prep and mid way shots.
    [​IMG]

    Here is another in the process shot. The foam has a good expansion rate of nearly 3 times it's spray rate so it rises up quickly. Not fun stuff to get in your hair, so protection is HIGHLY recommended. I'll put together a HOW-TO post on this later on.
    [​IMG]

    Finished product.
    [​IMG]

    Don't mind the pink lines, those are just the seam welding line layouts that I had in mind.
    [​IMG]

    And our quest for weight savings ventures on.

    We got so crazy with saving weight we began to play with different parts from different year Z's to shave even more weight.

    Here we took the cross bar (under dash) and weighed the two to see how much we actually saved by going to a NA 2+2 coupe bar.
    [​IMG]

    Here you the difference in pounds....not ounces!!! We did this with a lot of parts on the car, throughout the whole build.
    [​IMG]

    An odyssey battery will now be our work horse for the kick on duties from now on. It's lighweight and packs a punch. It also has a lightweight tray that also came with it. Picked this up from Summit Racing for a good price. Plan to lighten up that try by punching holes through it and dimply dying it. Crazy....maybe....but we gotta go there.
    [​IMG]

    Stock mirros are power and way too heavy. The plan was Craft Square but damn those mirrors are expensive. Ordered a set of Bomex mirrors, should be here soon. Lightweight and should shave us a few pounds over the stock mirrors and their heavy metallic bases.
    [​IMG]

    Here you see how heavy these truly are.
    [​IMG]

    We opted to kill the hood latch, hardware, cable, connections and even cut the bracket out under the dash to shave as much weight as possible. Aerocatch hood pins will be our hood unlock/lock system. We shaved nearly 10lbs collectively here.
    [​IMG]

    As we went through the entire car, I sent some of the brackets that I opted to keep off to powdercoat to pretty them up a bit. These were about all the only brackets that we will have left when everything is said and done other than a few others. These brackets tend to rust and I had a minute to send em off....came out good.
    [​IMG]

    At this point Charles Parks from Powertrix stepped in and offered up a Carbon Fiber Hatch that he'd been sitting on. Charles makes a lot of trick parts and is a track enthusiasts to boot so he knows what it takes to make speed. I received the hatch in a piano sized box and quickly opened up to find this amazing part.
    [​IMG]

    Fit was pretty damn good considering it's a race only part. Props again to Cparks for stepping up on helping me shed even more poundage.
    [​IMG]

    Now that we had all of our panels in, it was time to detrim and prep to send it off to body work. By prepping a lot of the car, I saved a lot of change myself.
    [​IMG]

    The body was good but in no way perfect. I wanted the body stream lined and free of all the dents and dings from years of abuse. If you look closely, you can see a lot of circled damage area. I also opted to delete both lines and things as I may try to fashion a custom side skirt/rear bumper air guide later to help stream line aerodynamics.

    [​IMG]

    From here I shipped the car off to paint to have it started on. Little did I know I would primarily be the one doing all the body work anyways. Anyhow, there it went.

    Here's the starting point.
    [​IMG]

    I started labeling all the connections on the main body harness and began to remove it as well. I plan to simplify this harness as well to shave some weight here as well.
    [​IMG]

    The entire body harness removed and layed out how it goes in the vehicle for reference. I suggest labeling all the connections as you remove it from the car so you keep your sanity later when installing.
    [​IMG]
    [​IMG]

    From here I began to cut out all the brackets, studs, welded in clips and clasps as well as anything else that we wouldn't need in the future.
    [​IMG]

    This may not seem like a lot of brackets and stuff but it is. This small amount of metal etc, weighed in at 2lbs and 6 ounces. We had 3 of these piles. Total we cut out another 8lbs and 2 ounces for the day. This is even over all the deletes we did over 6 months ago. This goes to show that you can always still find ways to shave a little more here and there. But I think this was about the furthest we could without cutting section of sheet metal out completely, which has crossed my mind. Rear trunk....I'm looking at you.
    [​IMG]

    From here we began to swiss cheese a couple of panels while also being followed by a dimple die to give strength to the hole we just made in a perfectly good piece of metal. This process is very popular in cup car series race cars that are looking to shave any and every ounce possible.
    [​IMG]

    After that, I spent the rest of the day prepping the Powertrix Carbon Fiber hatch for paint on the underside to match out interior paint that is soon to come.

    Before paint and prep.
    [​IMG]

    After scuffing, prep and final prep and paint.
    [​IMG]

    I was also cleaning out the extra parts bin and remembered that I had all my glass and assemblies from the doors. I wanted everyone to see what taken out of the doors. Keep in mind this does not even include the door catch system, wiring and gunk in those doors. Like i said in recent posts the doors were by far the worst part of this entire build for me.
    [​IMG]

    Lastly, recieved a package from Japan today that I've been expecting.

    The stock mirrors come in at 7lbs and some changes as a full assembly (see previous posts) so I wanted to find a substitute that both lightweight, functional and cool looking. I had been looking for these Bomex mirrors for an infinity and finally found a set. Had them shipped from Japan as I finally found a set.
    [​IMG]

    While being aero dynamic and function they are above all else. SSSSuper light weight. Both mirrors came in at 5.5 ounces which is ridiculously light weight, even lighter than the CF mirrors that I thought about picking up. I was very happy to pick them up and happy to shave nearly 7lbs by dropping the stock ones over these.

    Since I am stuck waiting for my aviation primer to come in, I decided to take the whole day and dedicate it to being innovative to cut the last of the last pieces out of the car.


    Examples like this bracket. It mounts up an interior body panel to the car. We will obviously never run interior in this Z again so we trimmed it. Believe it or not, I managed to cut another 4lbs out of the car just using this thought process throughout the car today.
    [​IMG]

    [​IMG]


    This is a bracket in the center of the car behind the armrest up high. Normally there would be a bracket here that would allow us to run a harness through it to the fuel pump and then onto the ABS system (located behind the passenger seat). Eventually I plan to simplify the ABS with a brake bias system after talking to Kuah at SPL and figure out how he did it for the SPL track car. For now we will simplify and ziptie it to the rollcage or fab a bracket to get us through paint/cure and the car up and running.
    [​IMG]


    Previously I mentioned that I cut out all the brackets in the rear. This is a better pic to demonstrate how it should look in the end. This is the final look before paint. Notice I started to paint the panel interiors, as it makes it easier to pass over the simplest face panels first on passes with the paint.
    [​IMG]


    Some how during the prep, I took a good cut to the hand. Just a reminder out there to wear protection at all times.
    [​IMG]


    Here is a shot of the cavity with some paint on it. The entire interior will be this color. This dark grey made sense as it's easy to refinish later. White gets way to dirty quickly. Black would have us baking in the summer days. And the regular gray was just to simple. This color looks great when done right.
    [​IMG]


    I finally wanted to clean up that whole area under and around the ABS to prep and paint it today as it's the biggest pain in the ass to paint around later. I didn't want to mask around it later and it look like crap so I simply lifted it and painted it now. Later we will mask inside the body lines to cover our old paint and new blend lines (an old body shop trick).
    [​IMG]


    With the unit raised as a whole I finally had some time to get the last bit of sound deadener out of there and clean up that whole area really well. I noticed a lot of track Z32 that still kept the ABS system never get in there fully. I wanted to take the time to get this done right.
    [​IMG]

    [​IMG]


    Working a little more at that sound deadener. After I got the sound deadener out with a chisel and a heat gun. I still needed to clean it up. Some paint thinner and a red rag work amazingly great to clean up the tar residue. Saturate the goo leftover and run over it, slowly it goes away.
    [​IMG]

    Final prep and paint done. Same area.
    [​IMG]

    Here it is done. We will give it a 48hour cure time before we get near it for anything but looks good. I am really happy with the way it came out.
    [​IMG]


    From here, I wanted to really take some time and simplify as much as I could under the dash. Even though it will all be covered by stock dash (which we will need to alter to fit of course), I wanted to take the time to cut out all the useless brackets that I missed here as well.
    [​IMG]

    I know it doesn't seem like we cut anything out but we did. Cut studs and smoothed them out, cut brackets under the dash that were no longer going to support anything and found a small amount of deadener mat hiding in the corner. For the record, an 80grit flap wheel does wonders on working down studs. I also took the time to clean up the floors with thinner to get the last of that sound deadening leftover goo off. The floors look amazing. Too bad they will probably be the first victim of an eventual need for a respray once we put some usage on this car.

    After some cutting, elbow grease and love.

    This is everything that we took out of the car today. Basically, it's the last of anything we are going to cut out of the vehicle. This was the last of the weight that I could see cutting out of the vehicle from here on. I wanted to keep going but I think I am just going too overboard at this point. I'll see if I can find a few more opportunities to shave a few more pounds here and there for you guys. But we are getting scarce at this point.

    From here I didn't want to throw the towel on a full weekend without doing a bit more, so I turned my attention to mod-ing the dash and door panels. The dash and door panels will be modified to fit and eventually covered in alcantara (a form of nova-suede) along with the arm rest. These will be the only panels left in the entire car when it all said and done.

    My first attempt at installing the dash prior to hacking it up. Not gonna work.
    [​IMG]

    [​IMG]



    The stock dash before cutting it up.
    [​IMG]



    I start by trimming off the panels that no longer will mount up to the body or stock under dash bar.
    [​IMG]


    After about 6 more test fits and alterations we finally got it to fit like a charm. I still utilizes 7 connecting bolts out of the original 11. Not bad. Fits like a glove. Also this really doesn't count as a weight reduction because everything we cut off the dash only came in at a mere 2 ounces. :)
    [​IMG]

    [​IMG]

    [​IMG]

    [​IMG]


    From this point I took the time to trim up the original stock door panels to basically just have glorified arm rests. Due to Texas sun the interior of a car on the track can get over 120 degrees. I can't see myself resting my precious arms on a hot bar or even a hot black pad so we opted to keep these. At a collective .5 of a pound with hardware, I think I can spare it.

    Me prepping the bars and area under the roof for the bar primer.
    [​IMG]

    And yes, I wear a respirator for all of this. Safety first.
    [​IMG]


    The bars sanded all down and pretty. Isaac is in the car sanding down more of the roof.
    [​IMG]

    As for the primer we used. It's called Zinc Chromate and it's the BEST adhering primer for raw metal. The only note I want to stress is the safety needed here. We used a full, no joke, respirator for this operation. The primer lays on as an ugly green which makes no difference as we will lay our Rustoleum paint over it later once we do one last scuff pad session on the interior before final paint.

    Here are a few pics of the Zinc Chromate Primer layed down.
    [​IMG]

    The primer on the A pillar gussets.
    [​IMG]

    Yes, I know there is spots missing on the bars on the underside. This makes no difference as we really just need it on the top to give the paint something to grab and prevent runs when laying down the paint later on.

    This required a lot of prep. Basically it went.....scuff...air blast the chassis.....vacuum.....scuff....air blast the chassis....vacuum some more...scuff yet again....air blast....vacuum.... now hit it the entire interior with a surface prep.....wipe off the surface prep.....one last vacuum.... and begin masking everything off for paint...then finally paint.


    We start the day off with a scuffing since we already hit all the interior with all the sanding compound grits that we wanted. I want to say we finished off everything in a 320 grit before the red scuff pad were applied. I also spend an entire night grinding down all the sharp/rough edges that could catch someone's pretty little flesh when running over any part of the interior. Anywho, here we go.


    Mike D scuffing it all down.
    [​IMG]


    We start getting into more of the long other prep involved here.
    [​IMG]


    [​IMG]

    [​IMG]


    I plan on cutting out the rear floor to basically make a box section in the floor for a fuel swirl pot, maybe a fuel chiller and few other items so I'll cut out the floor at a later date. But, being a perfectionist I still had to option out to prep it all even though I am just going to come in here later and either plasma cut or disc cut out a lot of this spare tire area.


    Originally it was all covered in undercoating, which proved to be shoulder destroying to clean with sandpaper. So, we used out brains and used wax/grease remover with a few used red scuff pads and the stuff just fell off. After a few revolutions with this process, we came out with this. Reference the old pics to see how truly nasty it was on here.


    About halfway through cleaning.
    [​IMG]


    Finished.
    [​IMG]


    We start wiping down the rest of the car to prep for final paint.
    [​IMG]


    And now finally.....we lay the paint. We went through 9 cans total taking out time and doing it all right. I recommend hitting all the tough corners that are going to be hard to get later, first. This allows you time for those spots to dry and get ready for full paint lay on later. I like to start high up first on an interior and work my way out. This way I can lay inside the car shooting upwards and then get out to not paint myself into a corner (aka, stopping point). If you are doing a project like this, take the time to plan out the route you will use for paint. By just attacking it and not playing with the paint on other items first, you will not get the chance to see how thick/thin the paint can be. With this particular paint, I recommend a distance of a 12-18 inches while moving slow and steady when allowed. After everything....this is what we got.


    Outside to cure.

    Got around to painting all the hinges and plates that I previously sand blasted.
    [​IMG]

    All these things need to go in today or at least get a test fit as well as both doors and the Powertrix CF hatch.
    [​IMG]

    Here is the interior as I began the assembly.
    [​IMG]

    It doesn't look like much happened but most of the prep and PITA was getting the harness to run smoothly where I needed it to go. Later on, when funds are available, I'll try to have the body harness simplified for just running the essentials with a Painless wiring harness.
    [​IMG]

    Moving on to fitting the dash and few other things.
    [​IMG]

    Reassembly of the door's seals, hinges, catch and brackets.
    [​IMG]

    Test fitting the door trim panels after chopping them up. Later the dash, door trim pieces and center consoles will just get a wrap in the same material. Thinking Alcantara to keep it simple and clean.
    [​IMG]

    A mocked up idea of the interior trim panels that I will use in the dash and center consoles.
    [​IMG]

    [​IMG]

    Lastly threw on the Powertrix CF hatch to finish off the day.

    Had ordered these TRS from England a while back and they finally came in. These will be a weight savings replacement as opposed to the stock ones.

    Just one of the stock brackets on the scale with the hardware.
    [​IMG]



    This is the new TRS strap. Note the weight.
    [​IMG]



    Installed.
    [​IMG]



    This was the bar I had intentions on installing. It's a copy of the Do-Luck Rear Ladder Bar. I originally had it to add rigidity to the rear but later I plan on welding in a bar from cross member to crossmember to give the same result. So away it went. I'll probably throw it on the daily or something.
    [​IMG]



    I received this ARC induction box from another member a while back. I love this air intake and was on the hunt for it for a while. This will hopefully find a place into my project or my other one.
    [​IMG]

    Needs some cleaning. :)
    [​IMG]


    After marveling over the induction box I picked up, I went onto detail work for the night.

    From here I spent a lot of the night figuring out how the very few trim pieces were going to make their way back into the project. Originally this trim piece ran the length of the door edging. Since we run bars so close to the B-pillar I opted to keep edge guard while modifying them to fit. It's small mock up work like this that make for a good final product.
    [​IMG]

    Had a lot of small holes that needed to be plugged. Decided to put in some rivets for a cleaner look. Will use grommets to plug the holes where the Autopower rollbar was fit to.
    [​IMG]

    At the moment I am still struggling with figuring out how I will make a door handle release to the door. The stock handle will still perform all the normal duties from the outside...locking and opening the door from the outside. But inside I will have to run a cable to something to make it work. I had an opportunity to sit in Steve Millen's GTR and noticed that he ran a similar setup without using a stock handle but a cable system. He said, and I quote, "it was easy. Not hard at all to do yourself." So with that nod from one of the Gods of Speed, I will attempt to copy it from memory.

    Here is the stock latching system...simplified to the basics of course.
    [​IMG]


    This a closer look at the system. The blue rod handle fits to the outside door handle. The green rod handle is the one that we will need to loop to. The loop will need to run inside the door and come out somewhere mid interior door panel, so that I can pull it easily in case of a quick needed exit.
    [​IMG]


    Lastly, I threw in the new Kirkey seat in for some mock up to get a few things figured out. I am sure I will be taking this seat in and out a few times to make sure I get it right.
    [​IMG]

    Parting shot.

    Okay, so I've been trying and trying to figure out some of the more pain in the a** things to knock out.

    1) Slimming down the harness for all the things that I have now deleted.

    2) Installing some sort of door handle system to open and lock the doors manually. As well as come up with a handle to be able to close the doors also.

    3) Learning where to get lexan and how I am going to make it mount to the car.

    4) Making a release cable for the trunk of either just use aerocatch hood pins for the hatch and then have to make custom mounts.

    5) Start working on the aerodynamics.

    *********************************************************

    I didn't have a whole of time this weekend to dedicate to the track car but still got around to putting in some time.

    Picked this loop up from a Porsche site to be able to close the doors. I managed to take a license plate fastner and make it all work perfectly with almost no modification. Threw a little bling bling on there to make it look cool.
    [​IMG]


    [​IMG]




    From here it was on to the handle situation. I couldn't find a way to mount a handle and utilize the stock door panel that I cut up recently to make fit...so the panel got ditched. I like this better only because I can now get to the handle at a very easy, no effort reach. So when it comes to burning to death and staying alive, I'll take the first one. I ended up wanting to mount the handle high to make for an easy reach and also to be able to run the cables through a small valley that built into the door. This will make it damn perfect to run release cables into at a later date as well as keeping them away from damage in case of a serious side impact.

    Okay, so I took the handle and needed to drill another hole into it to make it a 2 bolt mounting point handle. This actually turned out to be very simple and easy to do. I highly recommend doing the same thing for anyone else out there. Just dumb luck to have worked out so damn clean. And yes, I know the handle is ugly but I will use another clean one. This one was simply for fabrication purposes.
    [​IMG]

    In the rear of the handle, I had to smooth it all down for a clean mating surface to the door.
    [​IMG]

    There were no holes here, so I drilled and then tapped a standard 10mm bolt pattern into it so that later I can mount another two "blingy" bolts into it after I get my upcoming set from VIP.
    [​IMG]


    [​IMG]


    [​IMG]


    Here it is all together. Easy to grab handle to close the door. And another easy to grab handle to pop the door open. Worked out great so far. All we need now is to figure out a clean cable release system and I am golden on this.
    [​IMG]




    After I knocked out the handles, I needed to cut out the rear floor area for two reasons. Soon I will be putting in a custom box section for a few things. And, I also plan on running a full lower rear diffuser that will suck up into the floor area, so this all had to go.
    [​IMG]

    Later we will clean this all up and actually cut even more out of it.
    [​IMG]


    From underside.
    [​IMG]


    Say bye-bye.
    [​IMG]



    I had a little time to put toward the body harness which is still proving to be a pain in the butt. This is all the extras cut out of the harness - wiper wires, defrost wires, 3rd brake lights wires, dome light wires, bose system rear speaker wires and rear washer bottle wires. This is the 3rd cut out of the harness, this all came in at 3.2lbs of wire and crud. So I figured we are maybe at around 10lbs cut out of the harness so far.

    Got around to finishing up the center console piece with the CF plugs. Came out okay.
    [​IMG]


    Also made a few of these around the car to cover up a lot of the holes I had that could easily find a bolt or screw falling into.
    [​IMG]


    Finally got in my other SFI approved rollbar padding from RPW. This padding is much smaller than the originaly padding, which is both lighter and allows me to see more out of the rear view mirror/front windshield areas where space is a premium.
    [​IMG]


    This is the completed roof padding. Finally knocked it all out.
    [​IMG]


    Got a few new things that came in for the project, like this hood vent. This will be added to the hood for some much needed cooling.
    [​IMG]


    Also, got these new power mirrors in a few days ago from Japan. Don't know what they are but they are both power and almost seems like a rubber finish. Very well made. These will go on the daily but just wanted to see them mounted.
    [​IMG]

    [​IMG]



    Finally, I got around to knocking out the doors. I ended up just deciding to use the original door handles and maybe I'll touch them up later but what the hell, afterall....it's a track car, so can't all be super nice.


    Anyways, This was a lot harder than it looked. Took forever to make it all simple, clean and effortlessly user friendly.


    I used a 3/32 high grade cable to attach from the locking release to the handle. The tensile strength on this stuff is something like 300lbs so this is probably overkill but what the heck.
    [​IMG]


    I then used a plastic roller to act as my pulled system/adustable cable tensioner. This was crucial to the simple design. Took me a while to get it all figured out. But I highly recommend this if someone is going the same direction with the door.
    [​IMG]


    The door had a stock slide adjuster hole originally in this spot. I simple made this my plastic roller point to be able to use the adjustability of it to add or reduce cable tension simply by moving the piece up or down. From here the cable simple ran through the door. A great way to keep the cable out of harms way.
    [​IMG]


    And here it is attached. Works like a charm. Now I just have to figure out a locking mechanism that is simple and we are all good.

    This is what I was starting with. I originally had the quarter glass windows but still wanted to use the moldings to get a stock look. I simply hate the way a piece of lexan is just drilled and riveted into the body. Doesn't look clean at all. So, I opted to strip away the quarter glass parts I didn't need.

    Anyways, this is our starting point. Obviously, everything is stripped off the quarter. Glues, adhesives, paints.....the whole enchilada...no hidden sins...to get us to here to this point, a clean mounting surface.
    [​IMG]


    From here I took the original glass and removed it from the body using a simple glass removal kit from Harbor Freight (around $15 for the kit) some time back. I then took the glass and removed all the moldings, permanently attached tabs and adhesives. All I wanted was the stock glass to start from the ground up for a mold. Even the tint needed to go as I need to make a template also of the glass black out area, so that I can make my lexan piece look exactly like this one.
    [​IMG]


    This is what I want. Just the glass....finally.
    [​IMG]


    Here is a basic mock up of what I want, using the original glass.
    [​IMG]


    Now that I have my glass out. I make a simple template.
    [​IMG]



    From here I took a piece of lexan that was the exact same width as the glass and cut out my piece using the above template. I used the exact same glass so that I could use the original quarter glass clips. These are important as they will allow me to simply clip in the rubber door moldings ( the same ones that everyone replaces all the time) that go over the glass. But the hardest part was forming, with a heat gun and by hand, the lexan to the same form as the oem glass. Here is the piece formed, this took about an hour for each quarter to mimic.

    From here I layed out my holes according to how the lexan will stress the most and of course taking the look into account as well. Gotta look cool too.
    [​IMG]



    After that, I simply added my drill points to the quarter via marker. Punched the sheet metal and drilled the holes to accept rivets later on.
    [​IMG]



    And here is mock up. Still have to paint the jambs with the car color later, buff and paint the quarter glass, install my lexan NACA ducts into them, lay down bonding adhesive and lastly install them. It will be a while till you see these in. But at least all the hard work is done. And.. YES I know it's rough but I plan on clean up the edges before install and also remember that moldings WILL be going back onto this lexan.

    So with that done, I moved onto the door glass. The problem I am running into with the door glass is mounting. I no longer run an interior track which is the whole support for our door, so I have to come up with either a bracket or reinvent the track to allow the glass to stay stationary. I may just make a lip that will run the length of the glass on the high part to give it some rigidity. But who knows, still working it out in my head.

    I also have a plan run a sliding door on the window as well, but have to figure out how to do that too. This glass will be a pain. But anyway, this is all I really got to on the doors.

    Took the original glass and simply removed everything to get a nice template.
    [​IMG]

    Here is the cardboard template. Not the stock moldings are staying place to still allow water to drain in the same stock way the car did originally. For the record, that cardboard is packaging from a Toyota bumper that I snagged from the office. Boooooo.......hissssssssssssssss..............

    Lastly, I worked on my layout for the rear glass on the Powertrix Carbon Fiber rear hatch. This is a bit tricky but nothing near as bad as the door glass will be. I will have to use a thick lexan so that I won't have to use a bracing in the middle of the glass, that will simply impeed my vision. So forming it, although minimal in angle, will still prove to be a pain. But hey, gotta make it look cool.

    Here is the OEM glass in place. From here I will build a layout of my holes in the lexan that is coming in shortly.
    [​IMG]

    From here it's a lot of measuring and game planning. *sigh*.....this took a while to get all those holes layed out perfectly.

    So, I traced my pattern on the back and cut out the film area that was going to need prep before paint came. I hit the area to be painted with 2000 grit sand paper and wet sanded it to make sure I got a nice clean surface.
    [​IMG]

    From here I threw on a paint after prepping the surface with a light brush of Prep-all. I estimated my paint flash time to be quick so added a hint of hardener and flex agent so that the paint wouldn't flake even under major flex.
    [​IMG]

    Finished product on the backside. Came out pretty well. I still have to cut out a small area for clear NACA Ducts and the OEM quarter glass moldings, but otherwise very happy with these.
    [​IMG]



    After that I began on the door windows. I still am working out how I am going to make this clean but either way I needed to get the lexan cut, edged and somewhat formed.


    My template.
    [​IMG]


    Cut out and edged for a clean cut. I like to hit the edges with a 320 grit to round them off. Makes for a clean feel to touch.
    [​IMG]


    One of many mock ups. Notice how straight it is. Has not been formed yet. Also, I had to tension clip it in, as it won't stay in place since it's so straight.
    [​IMG]

    Forming. I use a heat gun and few different methods to achieve this. Takes some time but worth it for a nice finished product.
    [​IMG]

    After forming and mocked up into place. Notice how it just sits into place like stock now. Doesn't need any tension clips to stay put. It still will require bracing to become usable though. Later. Happy for now.

    A while back I recieved a "copied" version of the skyline nose bonnet. I've seen this on a few alll track Z32's and liked it. BUT, I was never ever happy with the way people installed them or if they took the time to do it right.

    Unfortunately, the piece I recieved was ugly. The fit is hardly flush, the center reinforcements are off by almost an inch, the whole piece is thin and it came with some chicken wire mesh that is just laughable. So, like many fiberglass pieces, it was gonna need some love.

    My plan is to reinforce the piece later after I have the whole piece drilled for my guide holes, counter sink all the hardware for a clean aerodynamic looks and basically just redo the whole thing for the most part. Note, that a lot of pieces like this need reinforcement. I've seen bumpers from a lot of Z shops that are just too damn thin. They have no real structure to them, this leads to stress on the part which leads to cracking and failure of the piece. But I'll harp on that later.

    This is what we received in the mail. Looks good but from my experience with fiberglass, it's a D- at best. But we are still going to use it.
    [​IMG]

    From here I hacked the piece down to make it look more simply as I am going to make the piece even more aggressive that it already is.
    [​IMG]

    I didn't want to do rivets as it just looks like ....well...crap. So I would accent the piece by using torque bits that will be counter sunk into the piece. This will require reinforcement on the underside as again, the piece is thin.

    Our drill hole. Note the thin fiberglass.
    [​IMG]

    Now, we countersink our hole to flush the face of our torque bit. Later all these bits will be shipped off to VIP Bolts for anodizing to make them stand out even more.
    [​IMG]

    I begin to layout the diagram. Yes, a lot of fasteners. Will look aggressive when it is done.

    The ABS actuator still needed a bracket for now, until later I figure out how to kill it out. In the mean time I had to fabricate a bracket to hold it into place. Originally we got rid of all 3 bracket beams that hold all the rear interior panels into place. These were no longer needed as we've gotten rid of 80% of the interior and brackets that hold them into place for a cleaner look and to shave some weight.

    So, i simply took the old bracket and cut it accordingly.
    [​IMG]


    After cutting and using a press on the end to make it look like a stock piece would.

    I ordered a reman steering rack and came in "okay" but was kind of pissed. When I opened it up a boot was already split. I had a set of new oem boots and installed them after the photo but still....for a brand new reman piece, that is kind of crappy. I am not telling who the reman rack was from but still, that sucks. PS- It was NOT Z1 before you all start going into your Hang-Em-High Mode.

    Installed the TeamTech 6 point harness Eye Bolts as well. This was more of a pain than I thought it would be. Took a while to get the spaces down and in the correct and proper way you are supposed to according so SASCA regulations. TeamTech makes an amazing harness, i picked this one up from Sean "The Stig" Farrah from one of his track car. I'll need to get it update as it's expired but it will work for a while until the Z sees competition and the need for date validation becomes an issue for the belts.

    Spent a full day working on forming the rear back window Lexan and still need to probably throw another 3-4 hours at it.

    This is before I started forming it. Straight as a board, this is how sometimes these are installed on track cars and they look like garbage without an angle formed into them.
    [​IMG]

    These will be the inner aluminum bar bracing for the rear back window. Later we will need to form them up a hair to accomodate the angle in the Lexan we still have to make. I will most likely hole punch these as well to shave off a few ounces and add some strength to them, but they are pretty stout for aluminum thin bar.
    [​IMG]

    Drilled and recessed to allow the lexan to sit flush on top of it for a good seal.
    [​IMG]

    Later we will have to cut/smooth out a section of the Powertrix CF hatch to flush these in.
    [​IMG]


    And now for the tears. When I was adding in the clear NACA ducts to the drivers side quarter window it cracked. It sucked. I was pissed and chunked it across the garage. The crack on the bottom is from my 100mph pitch into the garage wall, the crack was from the rivet exzerting too much force on the lexan and cracked it.
    [​IMG]


    But, I have a plan......I am going to one up this design with a CF NACA Duct, step up the thickness by .10 on the lexan I'll use for just this side and lastly install a set of small SS nut and bolt combo for the duct to fastened in. I was SOOOOO freaking pissed that it broke but I figure with failure comes the opportunity to make a better product. We shall see.

    Here we took the cross bar (under dash) and weighed the two to see how much we actually saved by going to a NA 2+2 coupe bar.
    [​IMG]

    so the 2+2 NA crossbar is lighter than the slicktop crossbar?

    Carbon hatch is nice
    Seriously - How to do it propely from the start

    My car looks like your first photo - but im doing the street use thing

    For the USDM it seems it is. The TT coupe was actually lighter than the slicktop coupe version we weighed as well. But there are minor differences in the column mount, nothing that can't be modified easily.

    Awesome build so far. How light is this thing going to be?
    Next update please!!
