I am also interested in a Ford GT Driving School,,,
Here's my story on driving school. Take the Bondurant 4 day class (
www.bondurant.com). You will be forced to drive three days in the sucky Corvettes. They are nice cars and fun on the track but my car had about 4000 miles and was falling apart. OK, rode hard and put up wet but I would expect the door panels to not fall off.
That aside, the last day of the 4 days is in these totally awesome little Formula Mazdas. These are the most awesome little cars you will ever drive, similar to an Ariel Atom except scaled down but wickedly fast for their size. And they got no nannies. The Corvettes have stability control and traction control to keep you save. The Mazdas are 1/2 the size but nothing to keep you from screwing up (like the GT).
After that class you can get a regional SCCA card as it is an accredited class that lets you go without instructor screening.
OK, so do that then do the advanced class. On that one you can bring your own car. It was my plan to do the advanced class this spring but the job situation and a Grand Canyon rafting trip are taking precedence. Their recommendation of the advanced class, with a huge amount of 1:1 instruction, is that you can drive your own car. For instruction you have to have harnesses on the passenger side. But their recommendation is to drive yours on the last day and go through their consumables - brakes and tires.
Miller Motorsports (Salt Lake) has a similar class setup.
At Bondurant when I was at the Barrett Jackson auction their lead instructor told me it was my gig. The advanced class is very much 1:1, and they will do what you want. If you want to practice oversteer recovery they will have you on the skid pad. I'll tell you from my first class you can practice heel-toe downshift for as long as you want. The advanced class uses the big track at Firebird raceway in Chandler, AZ.
