What is the current price of these arms and are they in stock or do you need to order them and then wait for them to be built?
What's to stop the thread from collapsing.... like it did on the other ones ? The design looks the same except one end can now swivel. No offence Penno, but a few thousand K's of track testing doesn't mean squat if they're going to be fitted to a road car I'll stack NSW potholes up against anything a "billiard table" race track can throw at a zed
Price is around $500, EOIs being registered here http://www.aus300zx.com/forum/showthread.php?t=280852
The thread must be under load..... if the threaded section is used to lengthen/shorten the arm for camber adjustment (same as the earlier version) it must be load bearing.
I assume ... .... the pivoting design reduces sideways torque to near zero therefore load is only applied in a longitudinal axis. I'm not an engineer so please correct me if wrong.
I was refering to one of your earlier posts where you said something about a "lubricating system".... I thought then that the bearings must have only had a one sided seal, obviously thats been changed now. Sorted
K-Zed is on the money. Check out the vids john has linked to, in non-pivoting designs (such as Stillen which are similar http://www.stillen.com/product.asp?id=STICNTARM01&c=SU&year=1991&make=NISSAN&model=300ZX) the thread is under load in a twisting motion as the arm tries to travel through an arc. It can't do this with a non-pivoting arm so the additional torque is applied to the threaded section. Pivoting design means no twisting load applied to the threaded section as the arm is able to travel through arc. Vids if you can't find them in this thread (and it is a mess...) are in the first post of my ZRNT thread.
I keep hassling john about this but it is talking a while... The product is right but members indicated that pricing around $500/pair was too steep. Last we spoke about it john was looking at alternatives such as building a pivoting centre into existing aftermarket arms, as well as finding someone to build for less. Unfortunately it all takes time which i understand is frustrating for all, myself included!
I don?t think $500 is too expensive to a custom produce like this, epically with all the testing that?s been involved. We have been waiting for this for nearly 2 years now, its getting a bit silly, just bite the bullet and get em made....
I wish it was that simple, I'm sure john does too. If UAS had gone ahead and mass produced the first version you would all be driving around with a sub-standard product. Gotta get it right before you sell it! The version I posted up in October last year is perfect, but manufacturing is a balancing act... The $500 price was based on an order of 20+ arms with SFA margin for UAS, and based on responses so far it's just not economically viable. I would happily pay $600 for a pair, but I wouldn't buy all 20! The soloution is to shop around for manufacturing and look at alternative options as has been discussed (like sell a pivoting "upgrade" to go with midori arms, possibly discussed in the ZRNT thread). This all has to happen along with numerous other jobs and group buys and running a workshop six days a week. I sympathise with people frustrated by the wait, I am one of you! Don't worry it will happen, but it has to be the right product (got that part) at the right price (working on that one!) and this all has to be balanced against keeping the shop running.
if you guys want then in a hurry , http://www.conceptzperformance.com/...&Car_Type=300&UID=20090108230916114.76.151.57 about 300$ will get you a verry good set , in your hands in 2 weeks
Umm not the same thing dude. Those arms you have linked to do not pivot and will eventually break like every other aftermarket camber arm on the market. The UAS ones are the only pivoting centre design anywhere in the world.
Possibly the best of that type of arm available ATM(but definitely nothing like the pivoting arms that UAS are developing, and definitely inferior to the UAS type).:zlove:
JP you told me that these must be used with rose jointed radius/tension rods, why can't you run these with stock radius rods with urethane bushes in them?
I had this discussion with John back in MAY. There was a failure of a pair of the arms which was badly bent in the centre. I suggested the application of these is fine but you must remove any forward/aft movement of the arm. The pivoting action of the arm doesnt remove the need to eliminate back and forth movement. In fact the member who had the issue removed them and returned them to UAS. Refitted the Original genuine Midori arms and as I saw as he was adjusting them, found they where in fact BENT AS WELL. But to a lesser extent. As the UAS arms are solid bearing exactly like other upper arms including original Midori style. This movement WILL BUGGER/BEND ALL OF THEM JUST THE SAME. The only way to eliminate forward/aft impact movment is via rose jointed tension rods. Expect to bend ANY of the aftermarket bearing based arms unless you have these. The only arms that can be used with bushed tensioned rods are those which has urethane/rubber inserts in them like the Stillen for example. As the bearing can take some for/aft impact movement within the rubber bush and cushions the bending force exerted on the centre section of the arm.
