Here's an interesting event. The "Drift" part is what you'd expect. The Time Attack is essentially an autox on the track. The track in this case is a good size go-kart track, check this out:

driftz240@aol.com I did this last year, I think you can easily get 15-20 runs and the track is .8 miles around. I think it's a little more fun than a typical autox. Nice people running the event and it is a NASA sanctioned event.
