FWIW, tire manufacturers are also a source of info on acceptable camber settings. For example, Michelin recommends -1 to -3 degrees negative camber with Pilot Sport tires for optimal handling, according to a Michelin technical bulletin posted by TireRack. Yes, wear will be greater than with less negative camber BUT it depends what you are going for....

BTW, Michelin also provides tire inflation recommendations that differ from Mercedes.
