PERRIN Performance Engine Mount

PERRIN Performance Engine Mounts: Precision-Engineered for the Performance Driver

When engine movement robs your Subaru of power and feel, the solution starts at the motor mounts. PERRIN Performance — the Oregon-based specialist that has been engineering cutting-edge Subaru performance components since the early 2000s — approaches the engine mount category with the same precision and real-world testing philosophy that defines everything they build. The result is a lineup of engine mount kits that strikes a carefully calibrated balance between performance stiffness and daily-drive comfort.

What Sets PERRIN Engine Mounts Apart

At the core of every PERRIN engine mount kit is a body machined from 6061 billet aluminum, a significant departure from the heavy OEM steel brackets found on most replacement mounts. As PERRIN notes, most replacement mounts reuse the heavy OEM steel bracket, but PERRIN mounts are CNC'd 6061 aluminum brackets, making a stronger mounting surface for the stiff urethane mounts. Lighter, stiffer, and more precisely manufactured — these mounts mean business from the moment they leave the machine shop.

The bushing compound is equally thoughtful. The PERRIN engine mount bodies are machined from 6061 billet aluminum and feature 75A durometer bushings, providing enough vibration absorption for daily driving while giving the driver a feeling of a firmly connected engine and chassis. This durometer rating is the sweet spot that separates PERRIN mounts from both mushy OEM rubber units and harsh solid-mount race pieces.

The Energy Suspension Interlock Advantage

One of the standout engineering details in certain PERRIN engine mount kits is the partnership with Energy Suspension and their patented Interlock design. The PERRIN Performance engine mount kit features Energy Suspension mounts with a patented Interlock design; unlike OEM and Group N mounts, the unique shape of Energy Suspension's steel internals keeps the mount from physically tearing apart. This matters because small oil leaks or highly corrosive atmospheric conditions combined with extreme temperature changes will make OEM and Group N rubber mounts brittle and lead to failure — while the PERRIN Performance engine mount kit with Energy Suspension mounts features 75T durometer that is impervious to oils and other chemicals.

Real Performance Gains on the Road and Track

PERRIN engine mounts reduce motor movement, improve power transfer, and give drivers a more connected feel. On the performance side, PERRIN engine mounts reduce most motor movements, efficiently transmitting power to the ground — and this translates to improved launches during drag racing and autocross type events. Whether you're chasing tenths at an autocross cone course or simply want a more confidence-inspiring feel on a canyon run, firmer motor mounting is a foundational upgrade.

A clever installer-friendly detail also sets PERRIN apart from the competition: the PERRIN mounts use a bolt in place of the stud, which means you do not have to lift the engine up past the studs or get the mounts perfectly aligned to the transmission and subframe when installing the engine — a detail done specifically for the customer who is constantly pulling the engine out to add new parts, rebuild, change the clutch, or any other big engine upgrade.

Broad Compatibility Across the Subaru Lineup

PERRIN's engine mount kits cover a wide swath of the Subaru performance family. Ideal for autocross, track days, or spirited driving, these engine mounts are constructed from durable 6061 billet aluminum and feature 75T durometer bushings, providing the strength needed to handle high horsepower and performance driving — and the kit comes complete with all necessary brackets and hardware, so no additional purchases are required. Supported platforms include the WRX, STI, BRZ, GR86, Forester, Legacy, Outback, and Impreza across multiple model years, making PERRIN one of the most comprehensive engine mount options in the Subaru aftermarket space.
