Yeah, im pretty sure thats what helped cause it/why i keep cracking rotors too. Though I bough the pagid yellows which seemed to help last time, and now have semi slicks for next trackday in april, so might pull the abs plug out and try that as well.
Yeha I was doing warmup/down laps not using the brakes and rotating the wheels while parked up with handbrake off. The pad to the bottom had even less meat on it, like 1mm or less.
*the pad in the middle is just an oem style pad for comparison*
