Stoptech ST40 332mm vs 355mm

[Cyclops]

I was wondering anyone knows if the Stoptech ST40 M3 NON ZCP (332mm) kit has the same caliper and hat as the M3 ZCP (355mm) kit, just the rotor size is different? So the real question is that if I can get my hands on a 332 kit, would I just need to buy the 355mm rotors to make it a 355 kit? Or are the pistons a different size and hats a different size. I can't seem to find individual part number s for each kit to compare. Any, help is greatly appreciated.

What he said, Zeckhausen is awesome and will give you all the information you need. With that being said, from owning these kits the parts number for the calipers are different for the M3 between the ZCP and non ZCP cars (I think just the rear calipers??). But David will for sure have the answers to all your questions, he's a great guy!
