Might want to check the StopTech Street Performance pads. Supposed to be OK for light track use...they might be cheaper than the Z rated pads.
If you are going to do HPDEs on a regular basis (3-4+ a year) I would swap in some higher temp pads. It will save you money in the long run. For example, the PF01s will likely last you at least 3-4 weekends whereas you might go through an entire set of street pads in one weekend (very possible). I HATE missing sessions...so you have to factor that in if you cook a set of pads. How many sessions will you lose because you went home early with cooked brakes? I also HATE dicking with my car between sessions if I don't have to. There is lots to do. Check out other cars, talk to people, watch the action on the track, eat, get fuel, etc...
If you are just testing the waters to see if HPDEs are right for you, I'd stay with a FRESH set of decent brake pads...like the Z-rated.
