I had a hard time wearing out my original rotors with various track pads (dtc 70, raybestos st 43, pfc01) and two competitive NASA tt seasons. They were replaced at the 30k service. The moral of the story is that the oem rotors are pretty darn good.
I'm also finding that my 380mm stoptechs are holding up well but will most likely be replaced due to cracking before they wear out. I had some pretty bad luck with the pfc replacement rotors as well.
