I just the Wilwood "tan" pads for the street, not too "dusty", and work well when cold. I dont' need nor can get a race pad for my Ford rears, and just don't need an upgraded pad for the rear, even with Hoosier slicks. I do use SRF brake fluid. I have boiled my master cylinder, and overheated my clutch master too with lesser fluids in the past. But then slicks put a tremendous amount of heat in the fluid, and Chris and I brake very hard on the race track. We are not "coasters".
Ask for Robin at Pegasus, tell her hi from Hal, the Cobra guy in sC.
You could run the PF 80's for the street, but they are much dustier, and are not necessary. You need a pad that works well from the cold on the street. I have the SPF Wilwoods Dynalites, i can't recall if II or what at the moment. But the 80 pads last for ever, i am still on my original set of rotors, with over 50K miles and about 500-600 race course laps. So the 80's are obviously very gentle to rotors.
Let me know if you have any more questions.
