Subaru WRX STI Suspension Bushing Kit - Rear - COBB - Diff to Subframe Mount - 08-21. Replace the factory diff-to-subframe bushings to firm up the rear drivetrain and sharpen response.

COBB engineered this kit to limit rear differential movement under load, reducing lash for steadier acceleration, cleaner corner exits, and improved throttle feel. Fits 2008-2021 Subaru WRX & STI, including 2018 Type RA and 2019 S209, and also 2009-2013 Forester XT. Direct-replacement bushings with sleeves; press-in install recommended. A modest increase in NVH may be noticed.
