I am running DBA rotors which have paint indicators on them, although I must admit I did not pull the wheels to check it out. I am using Wilwood 600 fluid, and don't think it was boiling. This seems to be primarily a pad problem, so I will be switching to the Hawk DTC-60's as suggested by John George...who's to argue with the national champion? By the way brake balance and stopping power were excellent with the small rear brakes, at one point I missed a braking point going into the corkscrew and locked up all four wheels, going off track in a straight and controlled fashion. No apparent need for bigger rear brakes. If you can lock all four Hoosier slicks at will, you have max braking capacity of the package!
