Camber is the tilt of the wheel relative to vertical, and making rear camber more positive means tilting the top of the wheel outward. A shim installed with the thicker portion at the top changes the angle of the strut mounting so the top of the wheel sits farther outboard, rotating the wheel toward positive camber.

Moving the top of the strut rearward mainly affects toe and caster and has little, predictable impact on camber. Lengthening the front strut rod alters suspension geometry in ways that aren’t a straightforward camber change and can introduce other handling issues. Lowering ride height tends to increase negative camber on many setups because the suspension geometry compresses differently, bringing the top of the wheel inward. Therefore, using a wedge shim with the thickest part at the top is the effective way to push the rear camber toward positive.
