BMR Suspension designed the MM004 to be the perfect (100% bolt-in) motor mount for any power level or application (street performance, drag race, and road race) where engine deflection needs to be reduced. The factory hydraulic motor mounts are designed to dampen engine vibration, giving you the smoothest and most comfortable experience possible. Unfortunately, this does little to limit engine movement. This deflection means lackluster throttle response, slower reaction times, and less accurate shifts in manual-equipped cars. BMR's MM004 polyurethane motor mounts limit engine deflection, while isolating much of the engine vibration from the vehicle's occupants. This means you won't feel a big increase in NVH. The reduction in deflection leads to less wasted power as it's transferred to the tires, improving your driving experience on both the street and track. And less drivetrain movement means more accurate shifts as you row through the gears. The MM004 is also height adjustable. Simply remove the aluminum spacers to lower the engine a 1/4-inch in the engine bay. This will give increased under-hood clearance for a strut tower brace or supercharger, and a lower center of gravity for improved handling. When performance is a must, rely on BMR Suspension!.
