I grew up in paved oval racing. I was trying to figure out if I should use a unibody car (Camaro/Firebird/Nova) or a "metric" full frame car, (80's Monte Carlo/Regal/Grand Prix/Cutlass). You could get a basic ball park from someone that runs a car like yours, but you will want spring options for each wheel and wheel offset differences to choose from, and stager differences for the rear. Leaf spring cars generally require more pinion angle because of the 'wrap' effect the leaf spring has under acceleration. This would mean we could align the driveshaft from a side view inline with the tranny shaft and the pinion shaft with no angular deflection.

A very soft spring would need more compression rate and less rebound rate, whereas a stiff spring would need a lot of rebound rate and much less compression rate. If your vehicle of choice utilizes a McPherson strut style front suspension, then your 2 pivot points would be . If you find you need to tighten SUCH AS SPRINGS, SHOCKS, SWAYBARS ETC.
