I remember reading the rear pistons might be bigger?

That's correct Derek. The rear ZCP brake caliper pistons are bigger than the standard ///M rear caliper which is why I have to program the ZCP option after installing them on my ///M. I got that part. :)

I did a brief search on the ZCP brake upgrade and from my understanding, this is what you need for the standard M3 --> ZCP brakes

Front:
ZCP Caliper Brackets
ZCP Rotors

Rear:
ZCP Caliper Brackets
ZCP Calipers
ZCP Rotors


Notes:
The front calipers are identical and use a 60mm Piston.
The rear calipers uses a 46mm Piston vs the 42mm Piston on the standard M3.




For a swap to a non-M, I would need to look more on exactly what is needed. I know Kalim changed out a few things for his front brake setup. He did the kingpins and wheel bearings/hubs, and M3 control arms and tie rods. I'm not sure if the control arms are necessary.

Turns out I won't have to worry too much about cleaning my calipers since a good friend has offered to have them powder coated....they will be cleaned just before they get powder coated. I'll be going with either the glossy black or flat black. Right now I am leaning going with the glossy black but I have time to change my mind...:)

Maybe if I was 30 years younger Dario....at my present age....no thanks ;) I'll stick to glossy black I think :thumbsup

Gloss

- easier to clean a glossy surface
- it's what the CSL calipers looked like
