I drove on bald ass drag radials in the snow a couple times, I could drive them to Vegas again next year, as a last resort. Only thing I hated about them is that they're rather loud for a road trip tire, so... I'm thinking of bringing a 2-3 car caravan of friends. One for luggage and people (the Corolla), and one for some slicks (the Mk3). My car won't be 320rwhp next time though, I can almost promise you that, a street tire isn't gonna hold if my clutch will.
That said, maybe I'll cruise down to Utah or whatever that really high elevation track is here in Wyoming or maybe Colorado... I'm not sure exactly where it's at, but I know it's not TOO far. I'll definitely update if I can get into the 12's.
