I recomend the Bridgestone Potenza SO-3 tires. And a rear stage 2 (22mm) rear sway bar from www.GenuineSaab.com
for some extra handling.
Please take the learning curve on the car slowly. A post on Central a few weeks ago got locked. It was about a youngin who took his car way to fast around a curve, panicked and wiped out big time.
