The SPC rear toe ±0.20° shim provides a precise toe adjustment in 0.20° increments for twist-beam rear axles. This full-contact fixed-change shim pairs with camber shims to fine-tune both toe and camber, and up to two shims may be stacked per side for greater correction. It’s a straightforward option for predictable rear alignment tuning.
