just another option to consider. As I've said before, I'm new to BMW, so don't take my word as gospel, but I've had great experiences with SuperPro on other cars. These also add camber, although being that they're adjustable, you'll want to take your car to someone thats experienced with aftermarket suspension for your alignment, dealer or your run of the mill alignment shop may not know what to do with that unless they have a particularly knowledgeable tech. I'd recommend a race shop (should be plenty in the vicinity of Sebring).
One of the biggest selling points to me about SuperPro is that their stuff has a limited lifetime warranty (limited as in only to original buyer), even with competition use.
