Kumho Victoracer, www.tirerack.com good R compound autocross tire. Not much slower than the hoosiers, for much less money. the better choice if youre just starting to get serious, since they last longer, and dont flatspot as easily.

Hoosier A3S03, www.tirerack.com best DOT R compound tire for autocross. a wee bit faster than the kumhos, mainly because of better lateral traction and much less weight. They flatspot fairly easy though, so be careful.

both the kumhos and the hoosiers are VASTLY superior to ANY street tire. Even the falkens are at least 1.5 seconds behind on an ordinary course and usually more. Epic, since you'll be in Street Mod with your swap, you want to look at the kumhos. But id wait until you got a few events under your belt before spending the cash.
