You got good brakes right?
It's not so much about your car as it is about learning how to drive it. They'll have classroom instruction and driving instruction. Then I'm assuming they'll have run groups based on vehicle/driver ability so you won't be getting in anybody's way.
Cost is $160.00 and all the track time you want from what I hear. This came from a Vette owner I met at B.I.R. Wednesday night. I'll be getting more details soon.
