Nothing wrong with doing the drop for the looks, so long as you understand the tradeoffs. With that much drop, you'll likely be on the bumpstops in quick transitions, which will upset the balance of the car. I still think you are better off with a smaller drop with stiffer springs and no camber kit. If you want better handling, some negative camber is a good thing. Also, if you are stiffening the springs (which includes shortening them) you will need to upgrade your shocks. Stiff springs will blow out stock shocks.
I have no experience with any camber kits, so I can't offer any opinion on them.
