The Damond Motorsports Rear Motor Mount for the Mazdaspeed6 was designed to drastically reduce engine movement, take anything your MS6 can throw at it, all while keeping added NVH minimized.
This RMM starts life as a solid stout chunk of alloyed aluminum.Once it’s machined to size we add two pairs of off the shelf bushings sourced from the market leader of polyurethane bushings. The bushing pairs themselves are specified at different durometers, allowing both high and low frequency vibrations to be absorbed, throughout the entire RPM range. The sleeves housed in each bushing pair are the appropriate length for optimal fitment on the Mazdaspeed6. This means no cutting out the rear tabs in the subframe, and no bending of the triangle support bracket that fixes the mount to the transmission.
