My suggestion if you only have 400 to play with is to just buy some good tires, a decent set of tires in 15" will run 400-500, and you get a lot more for your money with tires than you do rims. keep your eye out in the B-S-Tor on craigslist for some cheap stock rims. for the price of a decent set of light rims you can do alot of other modifications that will help a lot more than some light wheels
I am in STU class right now. I have already made some other modifications to the car before I started autocrossing. No matter what I need a second set of tires because I don't want to trash my touring tires which are nearly new. At this point I'm thinking of holding out for a good craigslist deal. If I am going to buy rims I want to try and get something that I will not need to replace again later.
