Hawk HPS / HP+, i've run both on the street and at Watkins Glen International [WGI]. I'll assign them each a number, 1 is worst, 10 best as compared to generic street pads
Generic / HPS / HP+
Cold Bite: 10 / 8 / 6 Dusting: 10 / 7 / 2 [lots of dust] Fade: 1 [lots at temp] / 6 [at temp] / 10 [none] Stopping performance [cold]: 10 / 8 / 6 Stopping performance [at temp]: 3 / 5 / 8 Pedal effort vs. brake force 10 / 8 / 6 Other Comments-threw in a set of generic pads for a 40 min session [my HP+ were gone and another guy gave me the generics] and went through them in the session. Also tried HPS, gone in a day [4x40 min sessions] decent until they got really warm then started to go away. HP+ are decent on the street but not optimum, don't take too long to warm up and exhibit zero fade. They do blacken my wheels with dust and don't have as much bite as i'd like or brake force as I'd like. Ran CHUMPCAR a few weeks ago and the Subie was stocked with some expensive Raybestos pads which were amazing - no warm up, great initial bite, minimal wear and not too much dust. They didn't seem to beat up the rotors much either [sT-43 is the part number].
