You will need an adjustable panhard bar for the rear axle. This bar attaches on the frame on one side and extends across to the other side of the car where it attaches to the axle. The purpose of this is to keep the entire rear end from moving side to side while allowing the axle to move up and down through it's suspension travel. The panhard bar's end link attaching to the axle moves in an arc. Thus, the entire axle moves in a lateral arc as the suspension compresses. The same effect occurs when you lower the rear end as you are effectively squatting the suspension and that shifts the axle off-center. An adjustable bar allows you to recenter the axle after lowering.
