After driving someone's car on the track at the 2002 SE-R Convention in Phoenix who had Carbotech Panther pads, I decided it'd be well worth buying a track-only pad. I called up Carbotech and decided I'd order the middle-of-the-road Panther... the Panther Plus. Well, they didn't have the Plus but decided to try to sell me the XP's instead. I figured they were just trying to sell the more expensive one ($140 vs. $120) I balked for a second while thinking and the guy told me that he'd give it to me for the Plus price... sold! I put them on the car and the car handled flawlessly (especially under braking!!!) at the track. I was outbraking all kinds of other cars (I have a 95 200SX SE-R with NX brakes, SMC lines, NX master cylinder, and Panther XP pads) It was amazing. I finally decided last night to change the pads (the squealing was getting to me!) and they're hardly used! The pads look just about as thick as when I put them on! I got some great braking out of the pads *AND* they look like they'll last me several more events - especially if I use them for track-only like I had intended originally!
