Subaru WRX STI Bushing Kits - Rear - COBB - Differential Subframe Mount Bushing Inserts - '08-'21. A straightforward upgrade that firms the rear differential mounting for a sharper, more connected drive.
These inserts fill the voids in the factory rear differential carrier bushings on 2008–2021 WRX and STI, incl. 2018 Type RA/2019 S209. By reducing deflection under load, they curb wheel hop and keep power delivery more consistent. Bolt-in with the OEM subframe; no permanent modification. A small increase in drivetrain NVH is normal.
Features
- Direct fit for 2008–2021 WRX/STI, incl. Type RA/S209
- Reduces differential and subframe movement
- Works with factory bushings and hardware
