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.
