Dean at Fairlady products has AXXIS pads I have used them for one full season they have decent stopping power and are very rotor friendly. Dean also has slotted rotors that I run they are legal according to SCCA. Hope this helps.
For road racing, KFP Carbon/Kevalr pads are tough to beat. Very rotor (and drum) friendly, awesome stopping power. Lasts an entire season, if you use the Gold compound. Generates a lot of dust though. Bill Wessel and I both use these pads up front.
Hopefully this won't divert the thread too much, but would the Carbon/Kevlar pads work for autocrossing? My question is related to whether or not they work well when cold. Or do they required to be warmed up somewhat?
