I used these today for the first time in my Stoptech 332 BBK at the Streets of Willow. The pads have a great feel, very linear, easy to modulate, and (surprise) little dust. The cold stop ability is some of the best I've experienced with a track pad, and I was impressed with how little it took to get them bedded and ready for use. The best part was how little the pedal feel and ability to modulate changed over the entire heat range. Late braking at the end of a long (30 min) session was just as effortless as at the begining.
