Welcome to the boards! Hope you learn some interesting information (obviously you must want to or you wouldn't have registered, lol!)
Autocross is a lot of fun. I do miss doing it. I haven't done it in several years, my Z was fun, I took it there a few times, as well as my old Mustang II I had before I sold it. Once I got into sportbikes i never went back to it though... (though I've been tempted to get a dedicated autocross car lately).
Welcome to the boards, enjoy your stay
