Description

The Damond Motorsports Transmission Mount is engineered to provide a solid connection for your Mazdaspeed3's powertrain, reducing unwanted movement and wheel hop. This mount features a CAD-designed and FEA-tested construction, built with high-strength steel and machined aluminum for exceptional durability – the manufacturer claims "You can't make enough power to break this thing." The design incorporates specially oriented bushings to support the motor and absorb vibrations, allowing for stiff performance without excessive noise, vibration, and harshness (NVH). Constructed in the U.S.A., the mount features a machined aluminum bushing carrier available in anodized gold or black, paired with a high-strength, welded, and powder-coated black steel lower and top base. It utilizes OTS Energy poly bushings, with available stiffness options of Street (70a) or Race (88a) to suit your performance needs. All necessary high-grade fasteners and lock nuts are included. The unique bushing orientation and transverse design further minimize NVH and stress on the bushing flanges. This transmission mount is specifically designed for the Mazdaspeed3 and does not fit the regular Mazda3. Damond Mounts have been used on record-setting Mazdaspeed3 vehicles and daily drivers alike. An install guide is available.
