all weekend long you can get your car on the track at the Hotchkis Autocross events (if you pre-register) I'm not sure about show up and register though (check with Hotchkis.net)

4 doors, 2 doors, trucks or cars... it's not limited.

327 or 427, one color suits both Camaros

If you miss this opportunity, catch the next one and have some fun
