Alex, have you ever used an infrared temp. scanner on your rotors after you have tracked them? I was hitting upwards of 500°F in the pits after a session a couple weekends ago, but I have no clue what is considered hot.

2-piece rotors may be at least worth a shot to help shed some of the heat and transfer less of it back to the caliper.
