I'm thinking about trying my hand at autocross this summer. Right now I have a bone stock 19' GTI S. I've got the upgrade bug and have been debating a JB4 and a bigger RSB for fun dailying upgrades. If I'm reading the rules right a JB4 would put me out of GS into STH correct? A local guy typically has top 10 overall times in an 18' GTI in GS. It sounds like the only legal things in GS are one swaybar, tires with a treadwear of 200 or greater and shocks. I'm guessing the best plan is leave the car stock show up and see how I like it? Any recommendations for basic helmets?
