i think the stock rotors are junk, just had the wifes sway bar bushings and other stuff replaced at dealership ( still under warranty
) they told me she had about 2 % left on her brakes and not to even bother doing the rotors just replace them as the stock ones are junk , had it done but not there and my friend who did it look at the brakes says yes its times and then says boy these stock rotors are cheap crap ?? so i repalced them also
