Overview

The JBR rear motor mount is designed for the 2007-2013 Mazdaspeed 3. It is available in three durometer options: 70A for street use, 80A for street, Auto-X, and road course, and 88A for the stiffest option for street, Auto-X, road course, and drag strip applications. The 70A and 80A mounts feature a large 3-inch diameter bushing for durability and comfort, while the 88A mount uses a smaller 1.5-inch bushing for minimal deflection and maximum performance.
Show original supplier description
The JBR rear motor mount is engineered to significantly enhance the performance and driving experience of your 2007-2013 Mazdaspeed 3. Available in three durometer ratings – 70 (Street-RED), 80 (Street/Track-BLK), and 88 (Track/Strip-BLK) – this mount allows you to tailor stiffness to your specific driving needs. The 70 and 80 durometer options feature a nearly 3-inch diameter bushing, the largest available for this style of rear mount. This substantial size, combined with JBR's proprietary polyurethane formula, delivers exceptional performance and durability while minimizing the transfer of Noise, Vibration, and Harshness (NVH) to the cabin, ensuring a more comfortable street experience. For ultimate performance and reduced deflection, the 88 durometer mount uses a smaller 1.5-inch diameter bushing, providing unmatched performance ideal for serious street, Auto-X, road course, and drag strip applications. This motor mount is an essential modification for drivers looking to reduce wheel hop and achieve more precise gear shifts. The features include reduced drivetrain slop, improved shifting accuracy, and enhanced 1/4 mile times. Installation is a straightforward bolt-on process. The product includes the motor mount and all necessary mounting hardware. JBR also includes free shipping within the US and a Hassle-Free Lifetime Warranty.
