The stock tires are terrible on track IMO.
The PSS are a great combo tire between street and track but like David said, you need to maintain control and not overheat them by scrubbing speed with the tires.
I ran PSS on my 2011 STi for a season of track and 2 years on the street. IMO they were more than adequate and I run in the Instructor/Advanced groups at HPDE. They also have great longevity as I put about 20K miles including a season of HPDE on them and no real signs of wear other than the usual evidence of tracking them.
If you are overheating your tires on track you should consider running smoother as that will make you faster and wear your tires less
