Street Unit Performance Billet Aluminum Engine Mount Application: Mazda MX-5 Miata Years: 2006 - 2008 Part Number: SUMX5AMM Street Unit Performance motor mounts are completely redesigned from the OEM mounts and engineered to provide the user with maximum benefit without excessively increasing vibration. They are CAD designed, CNC machined out of billet aluminum and the bushings are 62A durometer urethane (recommended for daily driven vehicles). Upgraded "Race" bushings are also available with a higher durometer recommended for high horsepower applications and/or predominantly race vehicles. The two piece aluminum and steel design is reinforced by two grade 12.8 bolts with a yield strength of 160,000 psi. The 2 piece aluminum/steel design is stronger than a 1 piece aluminum or welded mount. The engine mounts are sold individually. Two engine mounts are required to replace both OEM motor mounts. You can add the second engine mount to your order at a discounted package rate using the drop down menu on the upper right side of this page. The mounts come standard in the billet aluminum finish with the steel bracket powdercoated black. Using the dropdown menu you can order the engine mounts entirely (both steel and aluminum) powdercoated black for an additional charge on 1 or both of the mounts.
