The SPC rear camber −0.25° shim provides a fixed negative camber change in −0.25° increments for twist-beam rear axles. It functions as a full-contact shim that combines with toe shims to correct both camber and toe together. For greater correction, stack up to two shims per side, delivering controlled, repeatable adjustments to bring rear alignment into specification.
