Got it. When I bought my CL500 calipers for only $150 they came with the factory drilled rotors (not useable on a Crossfire) which were diredtional left and right. It might be when they get replaced they don't pay attention to that. It is hard to believe that Mercedes would design directional rotors and then put two lefts or two rights on a car. I will check on this when I am at the dealer. I am thinking of OEM rotors becuase I like the way the OEM drilled rotors look and I know they are quiet. I have tried OEM, semi metallic and ceramic on the Disc Italia's and the ceramics were the quietest but I am still getting a squeal just before I come to a complete stop.
