Brake caliper adapters

So I've decided I need larger brakes which are rather expensive.

The cheap option seems to be brake caliper adapters using some stock rotors from either a R33 or a Z33. I found these ones from UAS: http://www.uniqueautosports.com.au/Parts-Shop/brake-calliper-adapters-(front)---300zx-z32-3285.aspx

Anyone have any experience with caliper adapters?






On another note, 250 seems a bit pricey for 2 small bits of aluminum that you could make on a lathe for 50 bucks. Anyone have any I could take measurements from and then get made up?

 

You're paying for Australia labour with the UAS units, if you like supporting local.

You can get similar from the US for less though https://conceptzperformance.com/czp...-nissan-300zx-90-96-z32-41z32-vp100_p_881.php

I think the Z33 disks sit in a slightly different position to the skyline GTR disks the UAS kit works with, not sure which gives more wheel spoke clearance.

Also, if you think a lathe is the machine you'd use to make those you're paying for the know-how as well as the work

Edit: Found it, the Z33 disks sit further out with 49mm from the out-board face (where the wheel mounts) to the furthest inboard face of the rotor, while the 33/34 GTR disks are 53.75mm. Just shy of 5mm isn't really a lot but it can definitely make the difference between fitting and not.

 

A lathe is not the equipment of choice here mate

 

cnc milling machine yeah? I'm going to be buying them, happy to pay that little bit extra to keep the car and myself and others that bit safer

 

Alright, point taken with making them

So if I'm worried about spoke clearance go with the GTR disks?

Do the disks differ much at all performance wise?

 

Yeah, I mean you'll want to weigh up price too, not sure if the discs cost the same but if you already know you're going to be hard pressed to fit the wheels you want then 5mm less spacer would be a good move.

Performance should be identical, they have the same diameter and thickness. It's possible that the cooling vents have a slightly different intake designs but I doubt anyone has done any research on that topic for these disks and it's only relevant if you're racing.

Did you want to talk about why you're looking at getting bigger brakes? You can get a decent performance boost just by running better pads. The main benefit bigger discs have is they can hold and dissipate more heat, but they're also a chunk of extra unsprung, rotating mass so not always the best solution (hindsight)

 

From experience, the spacer upgrade using stock calipers and larger discs is an aesthetic mod only. Didn't make a noticeable change to performance. Good pads and fluid go a lot further for better braking.

 

We'll physics says if I have larger rotors then the extra leverage makes me stop faster. Also the larger surface area should help prevent brake fade. But physics is known to break when it's most inconvenient.

So then if I got better callipers would that make a noticeable change? What have you done?

 

Larger rotors do have a leverage advantage, I'm not sure how significant, but unless your brakes are so weak you can't lock the wheels/activate ABS then stronger brakes wont help a lot. Changing calipers can improve pedal feel and control a lot though. Plus just getting a good pad compound will probably eclipse any leverage advantages.

For brake fade you should start by pulling off the dust shields, you have to deal with them if you get bigger discs any way and they make a big difference to cooling. If you're doing proper track days somewhere with lots of high speed sections like wakefield or smsp then you may well still end up needing bigger discs.

I mean, go with whatever you want, I'm running 33 skyline brembos up front so I don't even practice what I preach but I did toast the shit out of my pads with the stock set up at wakie which was the motivator, should have done the shields and some ducts first though.

 

Just grab the Akebono 370z front upgrade and run stock rear calipers with upgraded rotors on the rear. Been in a Z with them on all 4 corners and my face continued travelling forward while the rest of my body stopped with the car. For the price it's worth it. After this thread, I'm going to buy another set instead of the tt setup.

 

So is that the 370z rotors and callipers at the front and the 14inch(?) rotors on the rear? Where'd you get them from?

 

Yeah but I'd rather learn from your mistakes

 

Surely is. https://conceptzperformance.com/ake...rake-upgrade-90-96-z32-41.02.akn01_p_3218.php

Not sure of the rear rotor size, but its 14 for the fronts, calipers are almost the size of a football. Make sure you have wheels that clear them tho. If i was you, buy the whole kit front and rears with the rotors and adaptor brackets, works out to be around $2300 aud landed I think. But they do give the option of buying just the calipers and adaptor brackets individually, so you can pick up the rotors over here thru dba and save on freight

 

what are the option in terms of upgrades for the rear using the stock calipers?
I have a set of akebono fronts here and I'm trying to work out what to do with the rears.

 

Stock with larger rotors should be enough, that's what the guys at czp told me anyways

 

I'm assuming that requires adapters? >.>

 

whats wrong with a hammer and chisel whats wrong with you people some of you need jesus

 

I'm curious about the Akebono option, according to CZPs listing fronts are 4x40mm piston which is the same as the Z32 and skyline brakes, probably better quality units but still can't do much for pedal feel. If you want to stop on a dime all you really need is good tyres and a strong leg, then make sure your existing brakes are working evenly to get the most out of your traction.
