These solid rubber transmission mounts from Rogue Engineering are a great upgrade over the flimsy “hourglass” stock mounts. These mounts are plenty stiff enough to use in a race environment with a solid mounted shifter (such as a CAE), yet allow for enough Noise/Vibration/Harshness (NVH) absorption to save your transmission’s cast aluminum ears.
MSW’s Take: We’ve found that solid engine and trans mounts can create unwanted stress to the fragile aluminum ears and mounts. We’ve broken several due to attacking curbs hard or off-track excursions. These failures are race ending. Using a solid rubber mount like these from Rogue can save your race.
We use these mounts on all of our endurance race car builds and many of our sprint race cars. Solid mounts disadvantages often outweigh their benefits, and polyurethane mounts are often brittle and fail.
For a race, track, or performance car we recommend pairing these mounts with our Enhanced Engine Mounts. They can also be paired with new OEM engine mounts for a near OEM level of comfort.
Made from neoprene rubber, with a straight cylindrical shape. There is no through-bolt or external cup, which are a poor design and lead to unwanted stresses and NVH.
Sold as a pair with necessary hardware.
Fits most BMWs from E36 to present (excluding E9X M3 and E9X Xi models.)
