BMR Chevy SS & Pontiac G8 GT Motor Mount Kit (Polyurethane)

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 G8s and 2014-2017 Chevrolet SSs. BMR’s new motor mounts (MM300) are far superior to the bulky, oil-filled hydraulic stock motor mounts, which are designed for comfort, not performance. BMR manufactures its MM300 polyurethane motor mounts in its Florida facility from MIG-welded ¼-inch plate steel with 6061 billet aluminum machined spacers and 95-durometer polyurethane bushings. The kit is completed with Grade 10.9 hardware.

BMR Suspension designed the MM300 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 MM300 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 more power 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 MM300 is also height adjustable. Simply remove a single aluminum spacer on each side to lower the engine a ¼-inch and two aluminum spacers on each side to lower it a ½-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 MM300 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.
