Spent the whole day at Buttonwillow Raceway Park during the summer with my Cquence rotors. They did pretty well I must say. I wouldn't say that they're much better than blanks though. I got mine because they were priced well, local, and I needed a set asap. Brake fade was minimal, and there were no signs of cracking or warping after 15-20 minute sessions.
Some info:
Cquence slotted/dimpled
Hawk HPS all around
ATE Super Blue fluid
Mazdatrix SS brake lines
