I doubt they will give him the old rotors if they warranty them. However, if you do get them put me second in line. I get about 6 days use out of a rotor before I crack it.

Sorry Bob, they turned the old rotors. Nice job though. Lots of metal needed to be removed.

2017 GS w/ 7500 miles. Just got back from Rick Hendrick. All four rotors out of lateral runout. I'm told this usually occurs when the lugs are not equally torqued but there are other causes. Replaced them all under warranty . Also had them check for bent wheels, both rear wheels are bent. Won't cover under warranty but I expected this. Going to repair and replace with forged wheels. I'll use the alloy for winter tires or something.

Post this to C7 Mark, you're in C6 now.
Glad GM came through on rotors.
Shame GM won't accept liability for their awfully cheap C7 GS/Z06 wheels.

I always found these threads funny, but just for fun, I tried this bedding procedure a few times over the last 10,000 miles. It didn't work, of course. I just did a long drive up and down the mountain today really getting the rotors hot, doing the procedure, then allowing to cool. Then trying again. I probably did it 10 times over the course of 3-4 hours. Absolutely no improvement whatsoever.

I started to feel my warped rotors at about 15k miles. I finally ordered new rotors and pads, but I figured I'd humor these posts and try it again. Going to take measurements and videos of the rotors as I take them off.

First of all, this thread is about 12 years old - you should have started a new thread as it is against forum rules to revive an old thread.

Secondly, if your rotors are warped, the bedding in procedure won't do any good. The bedding in procedure is meant to bed new brake pads to your rotors, and sometimes to eliminate a squeal, not to straighten out/fix warped rotors. Even turning the rotors probably won't help depending on how bad they are warped, which sounds like they are pretty bad if you can feel it. You more than likely need to get new rotors.
