Info on 350z brakes? rear caliper piston size?

[fireslave]

I'm trying to figure out what the piston diameter is on the 350z brakes so I can plug it into some equations and figure out brake bias and such for some custom setups...

I know the 350z has 1 piston sliding calipers at all four corners.

The front piston diameter is 57mm according to the google searching i've been doing...

I haven't been able to find any info on the rears! if anyone knows the piston diameter out back, it would be greatly appreciated! thanks!

does anyone have any idea where to find these? does nissan publish them, or does someone have to measure them? i dont think the're in the FSM, but i've only seen the pages that shows the caliper disassembled.

Take your micrometer to any auto parts store and have them show you a front & rear remanufactured caliper.
