I have been to 7trackdays each 20min*2 and from the markers the front rotors need to be changed already, I will definitely need to weight them. The rears are holding on but given their markers status they don't have much left in them as well. My car is almost 24k miles on it. I can't understand the people who doesn't have problems with CCBs, I mean either they don't track or do something different which I don't know, to protect them
I will try to post some pics of my rotors when I have time.
