Perrin Transmission Mount
2002-2014 Subaru WRX / 2004-2021 STI
The PERRIN Performance transmission mount kit reduces drivetrain movement under hard acceleration, deceleration and cornering.
Why do I Want Stiffer Transmission Mounts?
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 Auto cross 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'ed 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 a proper interlock built into it. 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 disconnect from your chassis.
No More Shifter Wobble
During normal driving conditions you hit bumps and potholes in the road, you may notice your shifter 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 actually affect shifting causing mis-shifts! The PERRIN Transmission mount is designed to virtually eliminate this movement while still keeping NVH to a minimum.
The PERRIN Mounts are made from CNC'ed 6061-T6 aluminum, formed powdercoated steel and custom made polyurethane bushings.
Because our mounts are stiffer than your 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 your engine solidly connected to the chassis, versus having that sloppy disconnected feel.
5 Year Warranty
PERRIN Performance warrants to the original purchaser, all PERRIN products to be free from defects in material and workmanship within a sixty (60) months period from the date of purchase. *Some exclusions apply

-Lower rpm when you lug the engine a little bit the noise and vibration are definitely increased significantly. -More vibrations and increased level of noise when idling (but not too much) -Sometimes a bit more rallying noise comes through when you accelerate from lower RPM. Overall, it is a good piece if you don't mind some increased level of NVH and it is no where near unacceptable. I actually like more sound from the engine and transmission when accelerating.
Took me about 40mins to install and didn't notice any noise like they said in 1st 3 gears but I did notice increase mpg, when I saw the rubber bushing I couldn't believe it, because has a lot of play I feel
