Perrin Manual Transmission Mount 15-26 WRX / 15-21 STI / 05-09 Legacy / 05-09 Outback / 93-23 Impreza / 16-19 Crosstrek / 04-11 Forester | Stiffer Polyurethane Bushings | Transmission Mount
Overview
The Perrin Manual Transmission Mount is designed to reduce drivetrain movement during aggressive driving conditions such as hard acceleration, deceleration, and cornering. This upgrade is ideal for Subaru enthusiasts seeking a more connected and precise driving experience by minimizing transmission slop and shifter wobble. Compatible with a broad range of Subaru models including WRX, WRX STI, Legacy, Outback, Impreza, Crosstrek, and Forester, it replaces the softer OEM rubber mount with a stiffer, more durable solution.
Engineered with CNC-machined 6061-T6 aluminum and high-durometer polyurethane bushings, the Perrin mount balances durability and performance. The design includes an adapter plate to maintain proper driveshaft alignment on WRX models with stock 5 or 6-speed transmissions. Unlike OEM mounts that use rubber prone to degradation, this mount’s polyurethane bushings resist breakdown and provide a consistent, long-lasting connection between the transmission and chassis.
By reducing drivetrain movement, this mount improves power transfer to the ground, resulting in more accurate launches and sharper shifts—key benefits for drag racing, autocross, and spirited street driving. While the stiffer mount introduces some additional noise and vibration, many Subaru drivers appreciate the enhanced feedback and solid feel it delivers, reinforcing the connection between engine and chassis for a more engaging driving experience.
