What camera were you using?
I'm just using a standard Canon Camcorder with an Ebay wide angle lens on the front of it. It's mounted on an IO-port roll cage mount which does a good job of isolating it from vibrations.
My friend was using a Go-Pro camera this weekend with a suction cup mount and it was nice for doing a lot of cool shots like on the door looking at the tire, on the roof, trunk, wherever. If I were looking now I'd probably get that type of camera for track use.
