A Tighter Connection Between Engine and Chassis

The soft factory rubber transmission mount lets the transmission move around under hard acceleration, braking, and cornering, which can translate into a vague, disconnected shift feel and even mis-shifts in extreme conditions. The PERRIN Transmission Mount replaces it with a stiffer setup that virtually eliminates that movement while keeping noise and vibration to a reasonable level.

Built for Durability

Constructed from CNC-machined 6061-T6 aluminum, formed powdercoated steel, and custom polyurethane bushings, this mount is engineered to outlast the factory rubber design, which is prone to breaking down over time. An included adapter plate maintains proper driveshaft alignment on applicable models. Manual transmission only.

• Manual transmission only

The RallySport Take

A worthwhile drivetrain firmness upgrade for a 2015-2021 WRX or STI, especially if you’ve noticed shifter wobble or want more precise, mechanical-feeling shifts.
