I had the potenza S-03s on my RSX for a bit. The dry traction on those things was incredible, it was basically too much tire for the stock suspension. When I did get them to break away, though, they definitely went quickly. They also weren't that great in the wet - my Kuhmo Ecsta 712s had better wet handling & hyrdoplaning resistance. And it seemed like the tread wore down really quickly.

I think my next set will probably be the F1-GSD3s.
