I have a 2014 Z51. It's a daily driver. No track use. The other day I noticed that the front passenger rotor was showing extreme wear. The cooling slots on the face of the rotor can only be slightly seen. The face of the rotor is fairly smooth. There is still plenty of meat on the pads. There is a slight chirp/squeak when coming to a stop but nothing to indicate that a caliper is hanging up and no other signs of uneven wear at the pads and the brakes stop the car smooth and straight. The other three rotors appear fine. In 30+ years of driving I've never worn out a brake rotor. Anyway, I'll need to get new rotors. I'd like to stay OEM and maybe update to the new one piece. Where is the best place to pick up a set? Thanks.
