The SPC rear camber +0.25° shim provides a direct positive camber adjustment in 0.25° increments for twist-beam rear axles. It installs as a straightforward fixed-change shim and pairs with SPC toe shims to achieve precise camber and toe settings. For larger corrections, you can stack up to two shims per side to reach the required alignment specification.
