Road Racing/ Auto X
I'm pretty sure that's enough to put you into CP, also known as "Heavy Metal". Like I said there are some serious race cars in that class. We were the only car that was actually street driven, but we still trailered to events just in case something broke as the local SCCA chapter runs nearly an hour north of here.
Some day I'm going to have to get some of my son's video tapes back so that I can put some runs on DVDs.
