If Cal-tracs are an option I wouldn't waste the time or money on S/S springs and pinion snubber.

The whole idea with S/S springs is the front segment has virtually no flex - all that is left to the rear segment. So basically you now have a solid front lower link. The snubber acts as the upper link.. Tuning is limited to moving the front mount up or down and/or the pinion snubber gap.

Cal-tracs work in a similar manner - the front mono segment has a bit of flex. The lower bars are lengthened or shortened to affect the flex and subsequent "hit". But the advantage is that both sides are adjustable.
