FG4RR Rear Engine Mount

The Hasport FG4RR Rear Engine Mount is specifically engineered for the 2012-2015 Honda Civic Si, addressing common issues like drivetrain slop, lazy shifter engagement, clunks, and wheel hop associated with the factory rear mount. By controlling engine movement more effectively, this mount sharpens throttle response and ensures the drivetrain stays in its intended position during aggressive driving. This rear mount is offered in four distinct urethane durometer options to match your intended use: U62A (Street) for a livable NVH increase on daily drivers, U70A (Track/Spirited Street) for noticeable stiffness and better control with reasonable NVH, U88A (Race/Heavy Track) for significantly reduced engine movement and locked-in shifts at the cost of increased vibration, and U94A (Extreme) for maximum drivetrain control in dedicated track or race applications, prioritizing performance over comfort. The FG4RR is designed as a direct bolt-on replacement, utilizing the factory hardware points on the FG4 Si chassis. Installation requires basic hand tools and either a jack with stands or an engine support bar. The mount is built with quality materials to withstand heat, load cycles, and aggressive driving, offering improved longevity and consistent performance compared to the stock rubber bushing, which can sag and crack over time.
