I don't know too much about cars, so maybe someone could help me out.

My tires are nearly bald and I need them replaced SOON. Does anyone have any recommendations about what kind of tire I should get? I need something that won't wear out quickly, but still can afford the grip needed to take turns for those weekend track visits.

Also, where can I get a set of the standard BBS gold rims!? I'm trying to change my car to the traditional "blue and gold."
