Torsion bars and lower control arm set-up

Like Del and AJ said, leave the lower control arm pivot but loose until you have the ride height set, once you have the ride height where you think you want it, roll the car back and forth a few feet, it'll probably settle some, requiring you to readjust a little. Once you have rolled the car back and forth and the ride height is where you want it, torque the pivot nuts to 145 ft lb. If you torque the but before setting ride height, the LCA bushings can wear out prematurely
