Hello everyone.

Its been a while since I've had an Rx7 much less my old stock pile of spare parts. Hoping someone with a spare 4 pot caliper could take a few dimensions for me! Pictures would be greatly appreciated!

-Mounting points (width)
-Piston diameter
-Caliper width from mounting point to 'face' of caliper
-Rotor thickness (how wide of a rotor will fit)

I've searched for some dimensions, but seemed to find more speculation than anything else. Specifically this thread: https://www.rx7club.com/suspension-w...ensions-69384/

For those who are curious, I'm looking to fit these to my '88 Celica Alltrac. The brakes on this car are tame in stock form.

Thank you for your help!

 

Just picked up a set to get measurements from. If anyone has the master cylinder diameter on hand that would be much appreciated!

Once I take the measurements I'll update this thread for future reference of others.

I'm actually looking to upgrade the brakes on my N/A and came across the info above on a search here. I'm not sure if some of the info provided in the link is for the TII or the N/A, but it also provides you with more options for the MC/BB
