the centric high carbon rotors i am using look perfect. not a spec of rust. but aftert getting and installing a set of new BMW brand front rotors fro a guy parting an x5, all braking vibrations are gone. I am so relieved to go back to BMW Brand rotors and pads. best stopping poweer for me. I dont care about thebrake dust as I clean my wheels so much anyhow.
So I must have heated the Centric rotors up too much during the bed-in procedure. Last time I do that procedure. No one else I know does that and they have great brakes...
