I am going to do a brake conversion on my car and will probably use RX7 SP or current model brakes. Was just wondering if anyone knew caliper and disc sizes.

I know the calipers are 4 pots but I'm not sure of the disc sizes. 12 inch maybe??

 

They are 11.5" vented disc from and back. The front is a 4 pot, the rear is a single piston. This is US spec but I doubt if the Aussie version is different.
