PERRIN Performance Transmission Mount Kit

The PERRIN Performance Transmission Mount Kit is designed to reduce drivetrain movement during hard acceleration, deceleration, and cornering, giving you a more connected and precise driving experience.

By replacing the soft factory mounts with stiffer, large-diameter 70a Durometer polyurethane bushings pressed into CNC-machined aluminum mounts, this kit minimizes drivetrain slop and maximizes power transfer to the ground. Whether you’re launching at the drag strip or pushing through tight autocross corners, the PERRIN Transmission Mount Kit helps deliver more accurate and consistent performance.

Built with a thick steel base plate and heavy-duty hardware, the PERRIN mounts absorb extreme vibrations and noises while preventing excessive transmission movement under extreme loads. Unlike OEM mounts held together by bonded rubber and small tabs—which can fail—the PERRIN design features a strong interlock to keep your transmission securely connected to the chassis.

Key Features:

  • Reduces drivetrain movement for improved power transfer

  • Large 70a Durometer polyurethane bushings for durability and vibration absorption

  • CNC-machined aluminum mounts with heavy-duty steel base plate

  • Designed for aggressive driving and performance applications

  • Prevents mount failure with a robust interlock design

Why Drivers Choose FAST of West Chester

  • I can't recommend this place enough. Being able to trust a shop in the performance world is big. The 2hr drive to get there, is worth knowing the job will be done right. Very happy to have found this shop, to
    support my builds going forward.

    Donald Wojnar

  • I recently had the pleasure of working with FAST of West Chester for some performance upgrades on my 2022 WRX, and the experience was nothing short of exceptional. I opted for a Borla S-Type exhaust and Cygnus Coilovers, and the team at FAST nailed the installation, fitment, and setup to a T.

    Adam Cranston

  • The team at FAST are excellence in every way. First, I consulted with Dave on mods for my HPDE track car. He listened and advised me on the best parts & mods to achieve my goals. He was patient & gave me space to research the options presented & worked with me through several changes before we built. Second, the build execution was flawless, proper heat shielding, bracing and poly everywhere. All components worked as advertised.

    Bryce Budd

  • This place has been my go to shop for all things Subaru. From simple service to performance parts and tuning, they have been top notch.

    William Brunell

  • Excellent shop. They installed a Cobb Stage 2 DP and Whiteline Sway bars and end links on my 2013 WRX. The work was done right and clean. The estimate was accurate. They were very knowledgeable, friendly and gave me the straight scoop on exactly what I was getting for the money
    and what I needed to get where I want to be with it. I'd recommend them
    to any car enthusiast.
