There are always trade-offs, like dating an exotic dancer, one has to chose what is important, and what isn't.
I think on a light car, the PF 80's are just right. Seem to be gentle on the rotors, a bit "dustier" than the tan Wilwood pads, and i don't know why one would need any other pad. Wilwood makes an Axis pad, which is one step up from the tan pad, which is probably similar to the PF 80 compound, but on a street car, which has to have constant, instant friction even when cold, and hopefully not dust up too bad, one would want a pad that gripped immediately, and did not have to heat up to work. Brakes on a street car just don't get warm enough to safely use a race level pad.
I have heard the expression from folks with other cars running race grade pads on a cool day, out on the street, say " i jumped on the brakes, and wondered where the brakes went."
I don't think you need SRF unless you are running race tires, you won't build up that much heat with street tires on a "track day." But while expensive, at about $80 for 32 oz, you have to remember that the can is a lot larger than the typical autoshop bottle of brake fluid. It is important to change out the clutch fluid occasionally too, as it too gets hot, and deteriorates the clutch cylinder innards. Found this out the hard way. i will try to attach some links to some brake questions.
