Probably not going again until next year, it's VERY expensive! (Entry, gas to get down there and go around the track, fluid changes before and after, new brakes, breakfast for the girlfriend to make up for abandoning her and spending money, tires, etc, etc)
The brakes held up fine except for the right rear caliper, which boiled the fluid. I need to change both rear calipers and flush the fluid with something better then autopartsstorerus DOT4. Otherwise they were great, the Performance Friction's stopped the 4,000+ Lb beast from 135 very quickly! My second session was nearly entirely open track with nobody overtaking (though I did pass a few) and every straight was at top speed. They exhibited no fade and great feel and modulation.
The rotors still work well, though they don't look so hot (no cracks, just funny colored
) I might pull one off on the rear when I take the calipers off to have a look see.
