I've had my S03's for a couple of weeks now. Did a little "spirited" driving this weekend, and I'm pretty happy with them so far. They aren't as sticky as the S02's, but are decent. Trading off rain performance and tire wear for ultimate dry stick is ok with me. Still a daily driver.

 

Forget those stupid Potenza's. I didn't really like them so when I got my new Work Miester 18' rims, I bought 225/40 front and 255/35 rear Kuhmo's for a total of $585.00 from Tire Rack. And that included shipping to my front door. The tires aren't as aggressive looking, but man do they stick on the twisties! I don't see a reason for me to switch.
