My old pump gas Duster had 49.4 % weight on the rear tires and 50.6 % on the rear tires, it had coil overs and ladders bars with four holes in the front mounting brackets. It like the lowest whole on the street and at the track I think the lower bar on them was either level or slightly nose down. I did end up changing the rear Strange Egnr. single adjustable shock to their same shock that was double adjustable, that car liked them also, especially at tracks that were not the best on the starting lines
Try all positions and then decide which one on your car is the best choice.
