GrimmSpeed Engine Mounts: We've Completed The Ultimate Collection

GrimmSpeed Engine Mounts: We've Completed The Ultimate Collection

For Subaru owners who demand more from their vehicles, upgrading the engine mounts is one of the most effective ways to unlock better performance and reliability. From spirited weekend drives to high-intensity track sessions, your engine and drivetrain must stay securely in place to deliver smooth shifts, consistent power, and predictable handling. Unfortunately, factory mounts are almost entirely designed for comfort. Their sponginess is only good at removing vibration during daily driving scenarios, and tend to fall short when pushing your vehicle to the limit.  

With the addition of our New Engine Mount, GrimmSpeed now offers the complete set to bridge the gap between stock comfort and true performance. Our Engine Mount, Transmission Mount, and Pitch Stop Mount work together to deliver the control, stability, and precision you need without turning your car into a harsh, uncomfortable ride. Let’s start by breaking down the role of each mount and why it’s vital for your engine bay.

Engine Mount: Keeping Your Engine Locked In

What It Does: The engine mount is responsible for holding the engine in place and preventing it from moving excessively during acceleration, braking, and cornering. Factory mounts are made with soft rubber to dampen vibrations, but over time, they degrade and allow the engine to flex more than it should. This movement can lead to delayed throttle response, sloppy shifting, and a disconnected driving feel.

Why It’s Important: A solid engine mount minimizes engine movement, giving you more precise throttle control, sharper shifts, and improved handling. Whether you’re on the road or the track, you’ll benefit from a more connected and stable ride.

Our GrimmSpeed Engine Mount Specs:
We’ve developed our Engine Mount Kit to provide durability and precision without sacrificing comfort.

  • Material Excellence: Our mounts are made from machined billet 6061 aluminum and 10-gauge 304 stainless steel to ensure they’re built to last under pressure.
  • Balanced Stiffness: The 75A durometer Street polyurethane bushings strike the perfect balance between firm control and daily drivability.
  • Innovative Installation: We designed slotted mounting points that make installation easier when lining up the bolts, saving you time and frustration during installation.
  • Complete Package: Our kit includes high-quality bushings, zinc-plated Class 10.9 hardware, and everything you need for a full upgrade.

Our Engine Mount Kit is designed to reduce unwanted engine movement, giving you immediate feedback and better shifting accuracy without introducing excessive vibrations.

Transmission Mount: Keeping Shifts Predictable and Smooth

What It Does: The transmission mount secures the transmission to the car’s frame and limits drivetrain flex under torque. Stock mounts often prioritize comfort, allowing too much movement, which results in slower, less predictable gear shifts.

Why It’s Important: A high-performance transmission mount ensures that the transmission stays in place during hard acceleration, cornering, and shifting. With less drivetrain movement, you’ll enjoy smoother, faster, and more consistent shifts.

Our GrimmSpeed Transmission Mount Specs:
We built our transmission mount to lock down your drivetrain while keeping ride comfort intact.

  • Durable Build: Made from robust 6061 billet aluminum and 304 stainless steel, this mount can handle high loads without deformation.
  • Upgraded Bushings: Our 75A durometer polyurethane bushings are twice as stiff as Subaru’s Group N mounts and 16 times stiffer than the stock WRX mounts. This ensures better drivetrain control without a harsh ride.
  • Wide Compatibility: Fits both 5-speed and 6-speed manual transmissions, with an included adapter spacer to ensure proper fitment on 5-speed models.
  • Quick, Secure Install: We use an OEM-inspired press-fit stud that reduces alignment issues and makes the install process smooth and easy.

Our Transmission Mount improves shift accuracy and power delivery, making gear changes feel more precise and predictable—whether you’re cruising around town or attacking a race circuit.

Pitch Stop Mount: Controlling Engine Pitch for Maximum Response

What It Does: The pitch stop mount connects the engine to the firewall and prevents it from pitching forward and backward during acceleration, braking, and shifting. The factory pitch stop mount is often overlooked, but its flexible plastic and soft bushings allow excessive engine and transmission movement, which can hurt shift timing and throttle response.

Why It’s Important: By limiting engine and transmission pitch, you gain smoother shifts, faster throttle response, and a more stable overall driving experience.

Our GrimmSpeed Pitch Stop Mount Options:
We offer two versions to cater to different driving needs: a street version and a race version.

Street Version:

  • Durable, Lightweight Design: Made from billet 6061 aluminum and machined to reduce weight without sacrificing strength.
  • Protected Finish: The anodized coating resists heat and corrosion for long-lasting performance.
  • Strong, Balanced Bushings: 80A durometer urethane bushings provide excellent support while keeping ride quality in check.
  • Reversible Design: You can choose which laser-etched GrimmSpeed logo faces up for a personalized touch during installation.

Race Version:

  • Extra Stiff for Aggressive Driving: This version features 95A durometer urethane bushings, designed for those who need maximum drivetrain control on the track.
  • Same Durable Materials: Built using billet aluminum with an anodized coating for extreme durability.
  • Reduced Drivetrain Play: The stiffer bushings minimize engine pitch to near-zero, providing superior control during high-performance driving.

Both versions of our Pitch Stop Mount will give you better throttle response and more consistent shifts. Whether you’re looking for a daily driver-friendly setup or a race-ready mount, we’ve got you covered.
