I will be purchasing the Hankook RS-3 shortly but all Zinn2win's suggestions are spot on for what I have read. The Kumho XS are suppose to be very good autocross tires. The NT01 and NT05 are very similar and both should not be used in any wet conditions. The Direzza are suppose to be very good also but about $300 more overall over the NT05 or RS-3 for about equal performance.
