Never done it myself, but the Hawley school gets good marks from most. The Roy Hill school gets similar marks for a strictly doorslammer deal.
Both of them teach you some basics before getting in the car, then you do some burnouts, progress to some short launches, and then full passes.
I don't know how they structure the time or how many passes, but if there's an extended deal (more full passes) then that would be a thing you might want to consider. Probably an extra day.
I think when sledgehammer says Firechicken, he's referring to the Firebird. It's a common nickname.
I would think that they have all their cars built to accomodate tall people (or short). Just speculating, I'd think they'd be set up so that they could change things quickly by moving pedals, seat, and steering wheel to accomodate pretty much everyone. Seems like I saw just that in a article years ago, though I'm sure they use different cars now. Hawley has been doing this a LONG time.
