The SuperPro forward pinion differential mount bushing kit for 2013 Scion FR-S (motorsport version) replaces soft OEM pinion mount bushings that allow unwanted differential movement under load. The motorsport specification tightens differential location to sharpen throttle response and handling precision while still preserving acceptable NVH for many driving conditions. The kit improves control and service life for track‑oriented use.
