Hi Bob, Re: Road America and Northwoods Shelby Club.........
Yes, I've now run with them three years straight. Incredible amount of track time and a good, relatively sane group. I usually run in their 2nd fastest group.
I converted the rear gears to 3.55:1 so it's not too far off of your car. Also, remember that my brakes are your brakes!!! Mine are off a 1991 Mustang GT, so, for better or worse, we're supporting the same amount of friction material. The difference is that I'm stopping 2550 lbs with me in the car and a full tank of gas where you're stopping maybe 3400#?. They work quite well and with fresh fluid, they don't overheat.
I'll be there again this year assuming no conflicts. Maybe we'll both put on helmets and go drive some country roads!!!
Best regards, Tom
