Autocross is the sh!t, you're going to love it. Since you are probably a little nervous about going to your first event, dont be - its really easy to figure out what you're doing there (that doesnt mean you'll be fast, Im talking about knowing how an event works lol). Its a lot of fun! What color is your car? I'll look for you at some events (though I might not be running my max there... we'll see).
