This transmission mount from STi features stiffer rubber to reduce driveline twist and slop from engine torque. Keep your engine power channeled to your wheels! You'll experienced reduced lash and less jerking under hard acceleration. This mount is the same one used in "Group N" racing.
Fits all 2004-2021 Subaru WRX STI, including 2015+ STI. Also fits manual-transmission 2015+ WRX, and other six-speed manual Subaru models.
