As far as wheel fitment:
18" x 9.5 +35 ESR SR06 -- clear no problem and don't look ridiculously small!
17" x 9.0 +24 03/04 mustang cobra -- clear no problem
17" x 8.5 +30 ESR SR01 --clear no problem
16" s4 TII -- clear no problem
16" x 7 unknown spec 10 spokes --clear no problem
15" s5 GTU, s4 GXL, vert -- do no clear, but would clear by minor grinding of the caliper or 1/2" wheel spacer.
I had no aftermarket 15" wheels to test fit, but it looks like wheels without a step lip could fit without issue.
The rear are officially available! I am hoping to have the front kit ready to go in the next 4-6 weeks. Rear rotor diameter is 294mm, front will be 330mm, both same thickness as stock.
Great eagerly waiting on the front adapters so I can do f&r at the same time. I think I might've missed it which front rotor will be used with the front adapters?
Nice progress! I'm working on some Z32 proper rear setup but still use Rx7 stock rotors, modifying the bracket it could accommodate FD rear rotors. My hope is to ditch the integral parking brake system entirely from the caliper. not needed in this application.
ditch the integral parking brake garbage, go from sliding to fixed piston style, eliminate moving parts, go from iron to aluminum components, the hydraulics are already setup for AN fittings so adapting is easy, not to mention the brake adjust valve at the handbrake so this should be a pretty great upgrade! These reman rx7 calipers are getting worse and worse and I have gone through many a rear set through the ownership of this car come to think of it.
300zx rear rotors are 11.7" diameter a touch larger and do not fit on the rx7 rear suspension, factory vented rx7 rear brakes are 10.7" diameter, the overall thickness between the 2 rotors is 2mm and these calipers seem to be more readily available and similarly priced, sometimes even cheaper.
Some people put rx7 front brakes on the rear and run four 4-pot calipers but that seemed like overkill, ive searched other brake swap upgrades and nothing really works back there, some FD upgrades but you still have a similar caliper style as the FC so its not a big difference. STI/Evo brembos are impossible to find and 3 times the cost per caliper nearly. CTS V stuff is all 4+ piston ginormous and a lot off off the shelf solutions for 2 piston via willwood or brembo were either too large/small or even more expensive...
So now I have gone down this brake upgrade path and potentially can make kits in the future with the DMLS 3d printer for others so this may be a slow roll...
People have used these calipers on FC where they put it parallel to the existing caliper and use a standalone e-brake but I think that bracket setup isn't going to be robust enough for rally.
(stolen from the internet)
this bracket does fix a key issue though, placing the z32 caliper offset a touch rearward as the offset of the rotor to rotor hat are different between the two, so to center the brake caliper pads on the rotor you have to raise the entire hub surface by 5.5mm, so a spacer needs to be made to accommodate the hub bore of the wheel and the hub bore of the rotor.
Luckily 1 factory brake caliper attachment point bolts up and works out pretty okay!
see? not too shabby!
depending on your wheel offset you may also need spacers. for running stock wheels like me 10-15mm is plenty and with these ARP extended studs I don't think adding a little bit of spacer will cause issues, especially in the back.
I made a preliminary prototype for the bracket out of scrap steel and weld, its too ugly to share but will do a side by side with the actual milled piece I may contact you if you having access to a machine shop for cutting a few pieces quick if I provide you a 2d drawing or 3d stp file & etc.
I'm really surprised there aren't good rear brake options for our cars and the reman rear calipers are getting worse and worse each year.
another happy customer from templeton's kit ordered some 330m mitsi evo rears and the adapter plate, no dramas for fitment ! the only thing i did was turn down 3mm total from the discs edge to help with the clearance in the caliper, less filing needed as well!
once its all in the car and running ill update again, thanks !
