My rear rotors/brakes are due and I ran into some confusion between 2 sites while trying to order rear OEM rotors. I ordered the sport rotors before realizing that there are 2 different types of OEM Rotors (Sport, w/o sport) What is the difference? Can they be used interchangeably?

Hey funny thing I have a 2012 Audi A8L with 108k miles and I am due for rear rotors and brake changes for the first time.I did the fronts at 95k miles. I do alot of highway driving.

To answer your question, we cannot use them interchangeably and only stick with the non sport rotors and brakes in order to keep the same brake distribution on the non sport A8 due to calibration computer etc.

I buy my parts from:

They are cheaper and better priced and genuine audi parts also.
