Hi Paul,

I think most of the Z guys I race with use them. Pedal feel is good, they last a reasonable amount of time (CMP will kill a set but CMP is the hardest track we have on brakes), and don't seem to tear up rotors.

I've used the 10s and 12s, both were very similar. Carbotech has descriptions on their website about the compounds. I think with some volume discounting we'll be in the 130ish range per set.

I've not tried anything else but the Hawk pads and I like Carbotechs better than Hawk. But, brake pad choice is one of those really personal matters and it is hard to but quantitative data on preferences. Been using Carbotechs for about three years and like them.
