Megatron, what rotors did you have - rb slotted?
Went in to my mechanic today and found the front slotted RB rotors were warped as hell. That was from a total of two track days, one with the RB pads I mentioned earlier, and the other with the Hawk DTC-30 pads. He had to machine them down about 20 thousandths. I don't know enough about this to know how rotors get warped that quickly, but am guessing it has something to do with wrong pads overheating.
FYI the backing material to the Hawk pads was charred and crispy, so they definitely got very hot.
