Introducing Boomba Racing's All-New Rear Motor Mount for the GR Corolla!
Upgrade your GR Corolla drivetrain's rigidity and achieve a true motorsport-grade feel with the Boomba Racing Rear Motor Mount. The factory GR Corolla rear pitch stop mount is known for premature wear and is designed primarily for comfort, leading to a disconnected and vague sensation behind the wheel. This loss of driver feedback is especially noticeable in the shifter of the Toyota GR Corolla. The OEM mount allows for excessive flex, the engine tends to rock violently under heavy acceleration and hard braking, wasting energy rather than putting power down to the pavement. Upgrading to the Boomba Racing Rear Motor Mount is an excellent modification for track-day drivers and drag racers seeking a firmly secured engine for maximized power transfer.
These rear motor mounts are precision CNC-machined in-house by Boomba Racing from aircraft grade 6061 billet aluminum. Through our extensive in-house testing, we have chosen to use 70A durometer polyurethane bushings, as it provides an excellent balance of performance while keeping NVH (Noise, Vibration, and Harshness) to a minimum. Unlike our competitors, our mount features hand-poured, molded-in polyurethane bushings instead of pressed-in bushings. This design ensures a more durable motor mount, as the collar cannot rotate in the bushing and cause friction.
The mount is a direct bolt-on replacement that installs just like an OEM part, requiring absolutely zero modifications to your engine or chassis. Installation is simple and straightforward, with no need to support the engine.
Available in 4 colors: Black, Blue, Red, and Natural Aluminum.
