Ok I just warped my 3rd set of rotors in 60k miles. I have been using the stuff from oreillys and advance auto and I am finding them to be crap. Autozone lists a severe duty rotor but for some reason they can't get them. So this lead me to do a google search. I found pricing ranging from 75-150 per wheel for pads and rotors. Can anyone recommend a setup that they have used. The truck is a 2004 GMC sierra 1500 half ton. I have been getting 15 to 20k on the rotors but this last set only lasted about 10k but it was my fault. I got them way to hot hauling waaayyy too much stuff. Also hoping to retain stock calipers.
