I'll be experimenting with a different set of pads: Porterfield R4 for the track and Centric semi-metallic for the street. Really wanted to get a PFC pad, but they have nothing for this car yet -- maybe next season. Will provide some feedback on the R4 in a couple of weeks after the track.
FWIW, I've used the semi-metallic for years on my E46 M3 and they were great. Silent and no dust. Not quite as quick at stopping as the OEM pads, but plenty good enough for the street.
