SPC stackable fixed-change rear shims allow precise toe and camber corrections on twist-beam axles, changing toe in ±.10° steps and camber in ±.25° steps. Combine toe and camber shims as needed and stack up to two shims for maximum adjustment. These shims simplify repeatable alignment service by providing defined incremental changes to restore correct rear wheel geometry on compatible vehicles.
