Description

Part #: MM300H

Engine movement (deflection) is wasted horsepower, and that power is yours! BMR's suspension wants you to take it back with its polyurethane motor mounts for 2008 -2009 Pontiac G8s and 2014 - 2017 Chevrolet SSs. BMRs 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 -inch plate steel with 6061 billet aluminum machined spacers and 95-durometer polyurethane bushings. The kit is completed with Grade 10.9 hardware.BMR's 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. BMRs MM300 polyurethane motor mounts limit engine deflection, while isolating much of the engine vibration from the vehicles occupants. This means you wont 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.

The MM300 is also height adjustable. This will give increased under-hood clearance for a strut tower brace or supercharger, and a lower center of gravity for improved handling.
