flame suit on i did the research and read different posts for several hours. i bought 17z calipers off of a 05 cayenne. i will be buying pads to fit exact model. from what i read alot of ppl use the rotors off of an amg 55 (although i thought that was for a 350mm caliper)? also i heard rumors that a s5 rotor would work but since i only heard it from one source i am thinking it wont work. the setup i am currently contemplating is using front rotors off of a 2006 c230 sport and maching the holes from 12mm-14mm and the hub to 68mm. i plan on ordering by tomorrow please steer me in the right direction so i can have everything squared away. by the way i am planning on going with ebc redstuff pads. car is never tracked and my daily driver. cold bite is very important and obviously good consistent stopping power. thanks in advance.
