So after ten 20-minute sessions on the Main Circuit at Summit Point, WV, my brakes were pulsing pretty badly. I know they had been toasted a bit. The ones on the right were a little worse than the left. This makes sense when you figure the torque vectoring function is going to clamp the inside wheel on acceleration. (Summit Point Main goes clockwise) I just received 2 rotors from Amazon http://www.amazon.com/gp/product/B00J5DTH0W/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1 and a set of brake pads: http://www.amazon.com/gp/product/B00J5BJFS8/ref=oh_details_o00_s00_i01?ie=UTF8&psc=1 And they were the real FOMOCO deal, arriving in 2 days. Here are a few pics of the old ones... they had some crazing on the surface of the rotors, and the pads were pretty much gone. I'm glad I changed them before this week's autocross. I am disappointed in the lifespan, though. Yeah, I drove the living s out of them. But I did my best to let them cool down while moving, and the rotors warped anyway. Does anyone think these can be turned/saved for spares? The bottom line is, I can't wait until Hawk or some other vendor starts making pads for the FiST. Something less likely to become so roasty. <-- that's a technical term.
