Hi,

I want to swap the rear rotors from my z4 3.0i (294x19) for 330i rear rotors (320x22).
Won't this give problems with the parking brake? Do the stock parking brake shoes from the z4 rotors fit inside the 330i rotors (same diameter?) or do i have to swap the whole inside from the parking brake (brake shoes, springs etc) too?

I need bigger rotors at the rear because I bought some 135i performance calipers (at ECS tuning) when the were on sale (@$99/pc), and it turns out that they bolt on straight away! (maybe a little 1mm spacer required). But the calipers have room for rotors which are about 26mm bigger.
