The STI Hardened Gearbox Mount is produced by STI in Japan and has long been a valuable asset to many of the Impreza, Forester & Legacy models. Both BRZ and GT86 owners can now also benefit thanks to the same range of improved mounts now released from STI.

Manufactured from a much denser rubber compound than the OEM mount, STI's gearbox mount offers reduced flex in engine and gearbox movement, particularly under acceleration and hard cornering. The reduction in engine movement not only offers an improved drive through the gear lever but also channels engine power to the drive train more efficiently.

This mount is a direct replacement part meaning no modification is required.
