Perrin Performance Transmission Mount for 2002-2021 Subaru WRX / STi

The PERRIN Transmission Mount reduces drive train movement under hard acceleration, deceleration, and cornering.

Stiffer transmission mounts give you a more connected feel with your car. The PERRIN Transmission Mount Kit will reduce most drivetrain movement, which efficiently transmits more power to the ground. This means more accurate launches during drag racing and autocross-type events where you do not want drivetrain slop.

The PERRIN Transmission Mount uses custom-made large diameter 70a Durometer polyurethane bushings which are pressed into CNC aluminum mounts, held in place with large bolts and a thick steel base plate. The larger bushings allow the extreme vibrations and sounds to be absorbed while keeping the transmission from severely moving around under extreme loads. Another feature the PERRIN Transmission Mounts have is a proper interlock built into them. The stock part is held together with bonded rubber and a couple of small tabs, which means it is possible that the OEM part could fail and leave your transmission
disconnected from your chassis.

During normal driving conditions, hitting bumps and potholes in the road, the shifter may wobble around. This occurs because the soft OEM transmission mount is allowing the transmission to be thrown around from road imperfections. In extreme conditions, this can affect shifting causing miss- shifts! The PERRIN Transmission Mount is designed to virtually eliminate this movement while keeping NVH to a minimum.

The PERRIN Mounts are made from CNC 6061-T6 aluminum, durable texture powder coated steel, and custom-made polyurethane bushings.

Because our mounts are stiffer than stock transmission mounts, there will be some added NVH (noise, vibration, harshness). The noises can be described as more gear whine coming through the chassis. For most people this is pleasing, feeling a solid connection between the engine and chassis, versus having that sloppy disconnected feel.
