Lowering the ride height will add negative camber to the rear. For best results, you should add adjustable rear control arms to correct the rear camber after lowering your car. If you choose not to correct the rear camber, your rear tires will wear unevenly. Install the rear adjustable control arms and have the alignment corrected.
