Back from the track:
These tires are STICKY! They by far and away outperformed the PS2's on the track. It is warm in AZ today - low 80's and the track was nice and toasty. I started out with a cold pressure of about 38lbs and at the end of my first session they were at 45 lbs. I backed them off to 42 lbs hot and kept them there. They worked very well. The track that I was on was Firebird West. It is a small and technical track, built for bikes and better suited to small cars. I was filing the mirrors of the Evo's, STI's, Sky's, Miata's, etc on the track for all 3 of my sessions. I am very very pleased.
Specifically, they felt very planted overall with a fair amount of warning before they gave. They didn't howl a lot close to the limit but when they did come loose it was gradual and predictable. They peeled back very nicely and evenly. I ran 3 hard sessions on them and didn't even roll them up onto the sidewalls - no scrub whatsoever. I would say that they will probably not last a long time taking them to the track, they are soft to be sure.
