Rotors under warranty

At 26,000 miles I had my THIRD set of front rotors installed by dealer under warranty. Not warped, just under speck due to track use.

I'm a believer in long cool down periods, and based on the track, and where they throw the checker, I drive for 5 minuites or so after the cool down lap.

I just had my second set of rotors replaced in over a total of 2000 miles. Whoever says that these rotors cannot warp is very wrong. On both sets they found that the warping was over 1/1000 of an inch. That said, no questions asked warranty replacement

1/1000th of an inch is within spec.

It's best to get them checked properly by a precision engineer.

M3 brakes don't warp.
