Went with some 6 inch backspace wheels, judging by the known 12 inch tire patch. Scrub radius should be down around 1 - 1.5 inches. Should keep the power steering pump lively, and reliable.
I want to set the springs up as close this configuration as possible so I can send the force of my springs to the center of the tire patch that is needing traction during the course of a turn. Most especially the quick, hard dig out turns that always seem to be here, there and everywhere. It will help with body roll, and Adam should be able to floorboard and dig before the apex. Also, this will give me constant force on 17 inches of direct vertical travel. It will give the 4 link more side to side control and the heim joints, more reliability. This set up should give me everything I want. We will have more articulation than needed, but will limit the articulation with limit straps when we need to, or we can run them out for straight up rock races.
