As with many facets of the latest Mustangs, the motor mounts are designed to not only secure the engine, but to dampen out noise, vibration and harshness. There are engineers dedicated to improving the NVH of new cars to provide you with a smooth quiet ride. However, the features that keep things on the down low can also hurt performance.
When the fluid-filled factory motor mounts are subjected to hard launches and high rpm the engine and move around on its mounts more that you might think. This movement slightly delays the transfer of torque from the crank to the drivetrain. As such, the crew at BMR Suspension developed a set of poly engine mounts (PN MM007; $129.95) to steady the engines in 2005 and newer Mustangs.
“The factory mounts are designed to absorb noise and vibration for a smooth ride, but do little for performance. The BMR mounts are constructed from ¼-inch, laser cut steel plate, aircraft-grade 6061-T6 billet aluminum, and 95-durometer polyurethane bushings,†says the company. “The BMR Polyurethane Motor Mounts drastically decrease engine movement by replacing the soft rubber bushings with stiffer polyurethane bushings with little change in NVH.â€
Better performance with little change in NVH is definitely a win-win and better yet, the BMR mounts are said to be 50-percent lighter than the factory parts. They can be installed in 2-3 hours, and if you need an even more rugged mount, a solid upgrade is available (PNÂ MM006; $49.95).
