If you drop more than an inch you may want to consider a camber kit. It depends on what you are doing. On a track car, negative camber might actually help handling, but on the street I think the tires would wear badly on the inside corners. This kit will not only let you adjust camber, but also set toe much easier. It is a balancing act to get it set. A change on the camber arm and affects the toe setting and vice versa.
