You will have to read the manual on how Mercedes recommends reducing rear wheel negative camber. They don't even talk about positive camber and is probably due to hardly anybody ever experiencing positive camber, most always negative camber where the top of the wheels lean in toward the body. Also, a whole lot of Mercedes engineering doesn't make sense when you try to logically guess at what is going on. Its almost like they go against common logic to get to the end result, which calls for a very high level of intelligence to understand and then work on these cars. It causes a whole lot of frustration as well, until you begin to think like they do.
