well, that's fine, but I bought these because I was told they were the BEST rotors, and as I'd seen 150k on the last set of OEM rotors, which FYI were the ONLY set of rotors on ANY car I'd ever owned that DID NOT warp or require turning, I figured they were the way to go.

My driving style has not changed in the past 5k, and I"ve put 95k on this car. 90k no problem, the next 5k, problems.

No valid explanation yet,.
