My Cobalt XR3s lasted 1.5 seasons (about 15 days) on RB rotors, and the DTC-60s are looking like they'll last at least 2 full seasons (20 days). It's not the rotors. It's the pad. The R4 S is far closer to the Cool Carbon than it is to a full track pad.
Granted my car is about 300 lbs lighter.
The hell I don't! LISTEN, KID! I've been hearing that crap ever since I was at UCLA. I'm out there busting my buns every night! Tell your old man to drag Walton and Lanier up and down the court for 48 minutes!
