Unless it's very dirty, it appears to me the rear wheel on the passenger side is not actually an SRT-6 wheel. It's a Special Edition model wheel which is an SRT wheel painted dark gray between the spokes from the factory. If the back wheel hit a curb bad enough to damage the wheel an alignment is in order. Rear camber is not adjustable unless an after market kit/solution is installed.

BTW, it looks really nice all blacked out.
