Because sometimes changing the geometery of the rear suspension, with LCA relo brackets typically, the wheels will change horizontal position in the wheel well. Just how the 3 link is setup. In order to correct the thrust angle, if it's out of spec, the adj LCAs will allow you to move one side of the axle forwards and backwards.
