"Wheels",
One thing I forgot to mention (maybe too obvious) but for a dual purpose car setting up the car's suspension using coil-over Shocks would give you a lot of adjustability between valving and spring rates. After a race it would be pretty easy to swap out springs, or whole shock units.
On my LSR Street Roadster I used Aldan's front and back. At Bonneville I found that I needed to stiffen up springs to counter the rocking motion caused by the side wind gusts. This has not been a problem at El Mirage since we usually have a tail wind. Any significant side wind and it's too dusty to see so we get shut down.
Adjustability is a good thing!
