I know this has been done so I wanted to see if someone can help me out with this. I just finally picked up a set of cayenne calipers for the front on my s4. I need to know what rotors and lines I need. I am pretty sure I read b7 rs4 front rotors or c63 rotors but cant find the info again. I also think this is the same caliper as the 6 piston rs4 brakes as well is it not? What style lines would be good to know to but I think b7 rs4 lines would work. Any help would be greatly appreciate as I am lost and dont want to do trial and error and searched my brains out.

I also have the ecs tuning stage IV upgrade on my B5 S4. The rotor size is 352mm x 32mm, I hope this can help.

The S8 rotor that is 345mm is what others have used. I'm not sure what brake lines to use though. I would measure the stock ones for reference with the calipers test fited to get an idea of length.

so the s8 rotor from what year? The same one on b6 and s7 s4's? Please let me know. I want to get away from the ecs version as replacement rotors are crazy expensive.

I'm not sure what year of S8 rotor. The B7 S4 rotor requires some grindin on the caliper to work. The Allroad guys have done this brake setup alot. I would look there.
