One problem you might be having involves the pivot points of the lower control arms and the inner tie rod pivot on the rack & pinion. Those points should be as close to the same position as possible. If there is a noticeable difference in the pivots, there will be a lot of bump steer. You should be able to deflate or remove the air bags, and move the suspension through its full range of motion with little, if any change in toe. If there is a noticeable change in camber through the range of suspension motion, there are some geometry errors built into the system. One final check- - - -a line drawn through the upper and lower ball joints with the suspension at its normal ride height should meet the surface of the road approximately in line with a line drawn through the centerline of the tire tread. A variation of the intersection points is called "scrub radius" and it should be at a minimum for best handling.
