: Dick, I have started to take my M5 to the track and switched to Perf. Friction Z rated (not quite a race pad, new front rotors and Super Blue prior to going. I did two days at Thunderhill, a few autocrosses and 12k miles of driving on them and just replaced the fronts. My rotors have a small lip--whem are they kaput exactly? Going for an inspection II so I will have them measured. They are at least $100 for the front only which is kind of spendy. Next time around (after I use up this set) I have thought I should just run stock Pagids and then switch in the race pads (Cool Willy's, PF's whatever) for the track (I bleed the brakes anyway).
My question is on the rotors. How long do they last? When are they worn out? They are $90 each for an M5 unless I can find some good ones cheaper so it is not insignificant. So far the PF's have held up pretty well, no fade but a bit more effort on a 100 degree day at Thunderhill--but they never disappeared on me. Yes, they dust like crazy, especially at first, and I don't think they have been great for my wheels (another reason to go back to a total street pad for everyday). However, I will get those re-done in a year or two anyway. Any reason to have a separate set of pads and rotors for the track?
