Street Unit Performance Billet Aluminum Rear Engine Mount
The Original Mazdaspeed rear motor mount, created in 2007-2008.
Proven design with thousands of units on the market.
Application: MAZDASPEED 3, Mazda3, and Mazda 5 (AT & MT)
StreetUnit Motor Mounts are completely redesigned from the OEM mounts and engineered to provide the user with maximum benefit without excessively increasing vibration. They are CNC machined out of billet aluminum and the bushings are 62A durometer urethane. The two piece aluminum and steel design is reinforced by two grade 12.8 allen key bolts with a yield strength of 160,000 psi, topped off with locktite. The 2 piece aluminum/steel design is stronger than a 1 piece aluminum or welded mount.
