Performance Friction has several compounds, I have not tried all of them but have tried the 93,90, 01, and 99. I use the 93 for the front and 90 for the rear. 01 is supposed to replace the 93 and 99 replaces the 90. If you do not have plans to heavily track your car then I would use the 90 in front instead of the 93 since they reach their max bite at a lower temp. The 93s need more temperature before they bite so it isn't the best on the streets because you don't usually get them hot enough and keep them at those hot temps. On the other hand, I have never experienced significant pad fade with the 93s even when braking hard and often on the track. By the way, I use 93s on the street but I just have to make sure that I don't succumb to impromptu street races because I will not have the braking power in an emergency when cold. I currently have the 01 and the 99s but I have not used them long enough to make a conclusion. My initial impressions are that the 99s are good but I don't like the 01s as well because they seem to take a lot more pedal effort for their max bite. I will be testing some more.
Finally as everyone has said, they are dusty.
