I've heard great things about the Pilot Cup tires. No personal experience with them though. I remember Ford used them on the cobra conversion of their RS focus when the ran it against a lambo. They made special mention that the Focus had an unfair advantage at the track because it was running the Michelin Pilot Sport Cup tires while the lambo had P-Zero's.

you might try looking through the Corner-Carvers message board for personal reviews.
