If you look at any Mercedes or BMW, they all have noticable camber in the rear, more than most cars. Why, I never cared enough to find out, I guess it's a German thing. I have just worn through my first set of rears on my car with the lowering springs, and they are wearing about as even across the tread as I've ever seen. So, with that being said, the camber is not a bad thing. I know having a car with too little camber ruins the handling, so I'm sure the Germans did their math that way for a reason.
