Details: The Saleen was absolutely the body of choice for this class and

 track. I brought several other types, but they never even went on the car.

 The track was a little hairy until you got into the 50’s or so and then the

aero effect kicked in nicely. At speed, the car was locked in and did pretty

much whatever my inexperienced hands told it to do. Once at speed I found

myself wanting more gear to go faster as the car was handling it excellently,

but I didn’t have anything bigger than a 39 pinion.
