USUALLY....you don't need a camber kit unless your dropping over 2 inches....USUALLY.
Me on the other hand, I do need one, and I'm not dropped 2 inches. I'm not going to get one, but I do need it. I'm dropped on TEIN Super Street Coilovers, and went in for alignment last week. We could get the toe perfect and the caster perfect, but my camber was out maybe .35 degrees on all sides. That was as good as we could get it. That was very close to stock specs, but on the alignment CPU, we were still in the Red by a long shot.
Anytime you lower your car, the alignment goes out. Wether it be the caster, toe, or camber. You HAVE to get it done. So go in, get your alignment done, and see where you stand. You may not need them.
Dont spend $$$ if you dont have to.
