Engine movement (deflection) is wasted horsepower, and that power is yours! BMR Suspension wants you to take it back with its polyurethane motor mounts for 2008-2009 Pontiac G8. BMR’s new motor mounts are far superior to the bulky, oil-filled hydraulic stock bushings, which are designed for comfort, not performance.
BMR manufactures its polyurethane motor mounts in its Florida facility from MIG-welded ¼-inch plate steel with aircraft-grade 7075 billet aluminum locating lugs and 95-durometer polyurethane bushings. The kit is completed with Grade 8 hardware.
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 ¼-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!
BMR Suspension’s MM004 polyurethane motor mounts are available in red and black hammertone powdercoat for long-lasting good looks in your car’s most harsh environment.
Installation time is about 2-3 hours with stock exhaust manifolds (installation time may be longer with aftermarket headers). Proudly made in the U.S.A.
For hardcore drag race and road race applications where engine deflection needs to be eliminated, BMR Suspension offers the MM006 solid upgrade. These black anodized billet aluminum pucks replace the polyurethane bushing, making the MM004 into a solid motor mount. These are designed for max-effort application where NVH is not a concern.
