Guessing I need an alignment...?

^ sounds like he doesn't want to get summer tires let alone an autocross set of wheels/tires.

Probably not a good idea to start autocrossing (assuming the OP is new at it) on expensive summer tires though. Worse to go out and buy ax tires before you've learned the ropes. Better to tear up what you already have first and get all the mistakes out of your system. Coming to think of it, in these parts that's probably what all season tires are best for... tearing up. They suck in snow deeper than an inch and they are big compromise in summer for such an excellent car.
