I bought EBC redstuff pads and brought my RS6 to the local Audi dealer to install along with new rotors. I just got a call from the service coordinator telling me the pads do not fit. The tech said the notch did not fit the pin it hooks up to (I don't know which of the 8 pads have this problem). So I was forced to go with the OEM Audi pads. Anyone else try EBC??
