Turns out I warped my rotors ever so slightly, don't remember driving all that hard on my p85, but with the weight and build-up on the rotors from under-use, maybe thats harder on them? Anyway, Rocklin Service center took care of me (awesome service BTW, took care of a rear door handle just out of warrantly and replaced my rear drive unit without question when I complained about a little extra noise when I get on the on-ramps). I didn't see the value in spending $900 on a set of front stock rotors from Tesla when there has to be something better out there. I spent $200 a piece on Maserati cross drilled performance rotors that I beat the hell out of and I've never had a problem (much funner in the corners and mmmmm.. the sound!). So, I don't want to spend 8k on a big brake kit on a electric car that I don't drive hard (acceleration only) but am looking for something simple. Anyone have any ideas? I found a post that the fronts are 355mmx32mm, but am having a tough time finding options. Thanks!
