SPC’s stackable rear shims let technicians change rear toe by ±.30° using fixed-change plates designed for twist-beam axles. Combine a toe shim with a camber shim to reach the exact correction required and stack up to two shims for greater change. These shims provide a controlled, repeatable method to adjust rear alignment and optimize tire wear and handling on vehicles with compatible suspension architectures.
