Depends on what brake temps you run. Also how long are your sessions, what tires are you running, how much braking is used on track, etc.
For street pads, just use whatever you like. I run the BP 20s on my car, but the yellow stuff, Hawk HPS, etc are all good street pads, but they are not good track pads.
For track use I would look at the Wilwood BP30/40, Hawk DTC80s, Carbotech, Gloc, Ferrodo DS2500 might work as a dual purpose pad, Porterfield, etc. A good track pad will suck on the street. MY BP30s are really grabby on the street, but I can hammer the shit out of them on track. They did very good at Barber.
