Alright, this is the only thing I can't figure out (yeah, right) on this car, We've tried all different suspension geometry and adjustments I can think of, and I can't stop spinning the wheels all the way down the straight (dirt). Im already way over the weight minimum with my 250 pound posterior, so I really dont want to add a bunch of lead in the rear. 1/3 mile high banked clay oval, open 1200, in 4th gear with a 373 rear. Can't use 5th, I lose seconds off my lap time, but of course dont spin-em in 5th either.
