I have briefly checked the rules (NASA), but with my mods I'm pretty sure that I'd be running with much stronger cars. I'll see how Time Trials go. I think I'll build another car for racing. I really enjoy my MX-3 and don't want to cut up the interior for a cage. Or, spin out and crunch it.
You gotta pay to play.
Both my camera and camcorder are broken. I'll try to pony up get one fixed and post some pics.
If I ever get rich I'd love to haul the car to Road Atlanta, that would be a blast.
