2013-2023 Subaru BRZ M/T Black Transmission Mount Support by Perrin

The PERRIN Transmission Support reduces drivetrain movement under hard acceleration, deceleration, and cornering.

Why Go Stiffer? - The PERRIN Transmission Support reduces drivetrain slop and movement under hard acceleration, deceleration, and cornering, which allows your engine to transmit more power to the wheels. This means better, more accurate launches for drag racing and autocross-type events where you do not want drivetrain slop.

How it Works - The factory "T" shaped interlocking support does not fit snugly into the transmission support. The gaps around this "T" shaped piece allow the transmission to move roughly 0.5" in all directions. The PERRIN Transmission Support is a larger version of the factory piece, eliminating the gaps and reducing transmission movements. The PERRIN Transmission Support, will only allow 0.1" of maximum deflection keeping the back end of the tranny in place during extreme driving and giving the driver a positive shift feel.

Construction - Machined from 6061-T6 aluminum, PERRIN Transmission Mount Supports are hard-anodized black for superior surface durability and corrosion resistance.

Noise, Vibration, and Harshness - The PERRIN Transmission Support will stiffen your stock transmission support, adding some NVH (noise, vibration, harshness). For most people this is pleasing, feeling a solid connection between the transmission and chassis, versus having that sloppy disconnected feel.
