I don't know if the OP is talking about road course or drag, but those ain't gonna cut it on a road course.
*edit* Damnit, McButterpants beat me again!
BTW, I run TCE brakes on the front of my car, which consist of Wilwood 4-pot calipers and 13" rotors with aluminum hats. Pad changes are extremely easy due to the style of caliper allowing a quick change to a more track bred pad if wanted. I have really enjoyed this setup over the years, though it's only seen street use. Not that I haven't gotten them hot... /ubbthreads/images/graemlins/hsugh.gif
