What's a good tire and rim setup you guys use for autocross. I am trying to get a little more serious about autocross and wanna get a set of rims and tires just for autocross. Where can i get a good set of light rims for a decent price. I also want to get some sticky tires that won't put me in a higher class( if that happends) I am i class sts. Any tips or info would be great.
