Hey guys thanks for all the great info I never adjusted the torion bars on the car I've left them as is but now I ski that makes sense it's to high in the front

4 speeds and drag radials typically do NOT mix. You need the soft sidewall of the bias tire, not the stuiff sidewall of a radial. I'd get a pair of bias ET Streets 28x11.5 or 28x12.5 if you can fit it. A 28x12.5 ET Street is the same size as a 28x10.5 ET Drag slick.
