Subaru Type RA Suspension Bushing Kit - Rear - COBB - Diff to Subframe Mount - 2018. This COBB kit replaces the factory rear differential-to-subframe bushings on your 2018 Subaru WRX STI Type RA to tighten driveline response.

By firming the junction between the differential and subframe, it helps cut excess movement that can soften shifts and throttle transitions, delivering a more connected feel under acceleration and during cornering. Built for enthusiasts, it installs in the OEM locations. Fits 2018 STI Type RA and also works with 2008–2021 WRX & STI, 2019 S209, and 2009–2013 Forester XT. As with any stiffer bushing, a modest increase in NVH may be noticeable.
