The way I understand it the guys Autocross on the East Coast (Concrete) on BFG Tires and the Westcoast ( Asphalt) on Kumho. As I'm going to have to many Modifications to run in any Stock Class and I have Two sets of Wheels I intend to Use the Tires for Track use only. However I'd Like to Drive on em to the Track so they need to be Street Tires.  Any sugestions???
