What is the durometer of the polyurethane bushing?

This rear motor mount uses a 70 durometer polyurethane bushing. This rating indicates a medium-stiff material that balances performance with acceptable NVH (Noise, Vibration, Harshness) levels.

Will this mount increase cabin vibration?

Yes, installing a stiffer motor mount like this one can increase the amount of engine vibration and noise transmitted into the cabin. This is a common characteristic of performance-oriented mounts, trading some comfort for improved drivetrain feel.

What is the main benefit of upgrading the rear motor mount?

The primary benefit is a more connected and responsive feel from your drivetrain. It significantly reduces engine movement, leading to crisper shifts and a more direct connection between the engine and the chassis, especially under load.

Product Details

This rear motor mount from COBB uses a 70 durometer polyurethane bushing. That means it's a well-built replacement for your stock mount, designed to handle the extra stress from performance driving. When your stock mount wears out, you'll notice sloppy shifts and a general lack of connection between the engine and the chassis. This mount tightens all that up.

By using a stiffer polyurethane bushing, this mount significantly reduces engine movement under acceleration and braking. You'll feel a more direct connection to the drivetrain, which can make shifting feel more precise and improve the overall responsiveness of your car. It’s a popular choice for drivers looking to get more out of their Mazdaspeed3 or Focus ST.

Installing a stiffer mount like this can introduce a bit more vibration into the cabin compared to a stock rubber mount. It’s a trade-off for improved performance and feel. Make sure to check the manufacturer's installation instructions for any specific details or recommendations before you begin.
