Perrin Tranny Mount

Perrin Performance

You will need a Perrin tranny mount if you plan on doing some hard driving. Any racing vehicle is subjected to hard turns and constant shifting. When an Impreza or FR-S is outfitted with a Perrin tranny mount, it can corner and pick up the groove on the track more easily without the shifter wobbling.

Everyday vehicles are not as vulnerable to the inconsistencies a road surface provides. But for racecars, it can be the difference between a good showing and an early night in the garage. What a Perrin tranny mount does is enact a level of absorbance that keeps the transmission from inching away or shaking due to constant stress. It is both a safety precaution as well as a comfort upgrade. The Perrin transmission support mount works by using bushings as a shock absorbing median between the unit and the drivetrain.

The primary result is a reduction in shifter wobble. Thus, Perrin transmission support mounts do most of their bidding when the car is at a high speed on the track. It is easier to go between gears quickly without putting stress on the trans. Even when encountering bumpy road courses, the Perrin transmission support mount will maintain the current gear without the shifter slipping. There is enhanced stiffness that was not there previously. It also aids in maintaining a constant stream of speed over distance. That is why most professional racecars are given Perrin transmission support mounts immediately after the drivetrain is constructed.

The stiffness comes from the bushings. This aftermarket trans mount features polyurethane bushings with a 70a diameter. Perrin then presses them into an aluminum support for extreme stability. The bushings are also why an aftermarket transmission mount is useful for cutting down on NVH. They are custom designed solely for this purpose. After they are pressed into the aluminum the part is locked into a steel base plate. Once installed, the aftermarket transmission mount will not betray position.

Like all of their Subaru replacement parts, Perrin includes hardware and install instructions. You will need a lift or a jack with stands to safely install an Impreza trans support. If you are inexperienced it is recommended to have a shop perform the installation. Click on the “Shop Now” button to view Subaru tranny mounts for your car today.
