Are you looking for a setup for the street, or for the track? They are going to be two completely different approaches because the level of traction is so different between the road and a dirt track. The weight transfer causing wheelies in a high grip situation on the road should help plant the rear when accelerating on dirt. I doubt you will have wheelie problems on the dirt track.

An ideal setup on a high grip road will be low ride height with limited down travel, heavy dampening and springs in the shock package, and thicker swaybars. Unfortunately, a setup like this would slide around on a dirt track like it was ice.
