I've found that PS2s do not handle heavy braking very well and wear out fast on a heavy car. I wore out my fronts in 4 tracks days, and the rears were fine (not talking about outside edge). Sidewalls are a serious issue as long as hot pressure is maintained ~40psi IMO. As Skierman said, these are all nonissues for a first track day...
EDIT: I meant to write, "Sidewalls are NOT a serious issue as long as hot pressure is maintained ~40psi IMO."
