Rebuilt '69 Valiant front end

No matter where the torsion bar is adjusted (as long as you are not sitting on the LCA bumpers) there is no greater wear on bushings or a harsher ride. You CANNOT add twist to the bar. All the adjustment does is to lower the LCA away from the frame. I would lower the rear and inch or two. There are many ways to do this, but I would never reduce the spring rate. Front hangers (Mancini Racing Spring Hanger Set) are probably the best with lowering blocks next.

Also, the front end was not done by somebody who knows Mopars. It does look like it may be sitting on the LCA bumpers. You need at least an inch between the bumper and frame.
