Andy, I've got that issue if you want to see it. They did their test on a stock Impreza WRX (my favorite flavor of rice!) and used Kumho Ecsta 712 tires (the ones we've been talking about in another thread).
Bottom line, the Hawk HP + pads were comparable to stock at lower speeds, quite a bit better at higher speeds (ie, 90-0) and seemed decently matched performance-wise to the higher-priced brake kits (rotors, pads, calipers) they compared to.
The Hawks did fade more than the full kits (heck, at $130 versus $2k+, what do you expect?) but less than stock - which is important on the track...
