Contrary to the above(
), I like the Performance Friction PFZ Pad... They are great on the street, do well with short spells of heat(autocrossing, NCCC type one timed road course lap), and if you buy them from autozone, have a lifetime warranty. They dust more than stock, but they really suited my driving style. I've run the Porterfield R4S, Hawk HPS, and they are very similar to the PFC. The PFZ is definitely more aggressive, but I didn't find them to have any low temp bite issues. Of the three mentioned above, I think that the R4S has the worst low temp bite. Amazing how opinions are like a**holes, eh???
Not sure if this link will work:

Hmmmm, it seems Autozone changed their warranty. The PFZ are no longer lifetime, but two years. The PFC are lifetime however. Anyone who tracks their ZR-1 will go through a set of pads in 2 years though..
I've wanted to try the PF 97 or 01 compound for track days, but the ZR-1 is pretty much retired. Quite frankly, the stock Z06 pads/brakes are pretty damned good for factory equipment(using street tires). You go through rotors like candy, but the calipers/pads are leaps and bounds above the C4 J55 brakes. Once I get some Hoosiers, I'll be trying the PF 97 in the Z06 and see how they are.
