Street Unit Performance Billet Aluminum Rear Engine Mount
Application: MAZDASPEED 3, Mazda3

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.

Benefits of Street Unit Engine Mount Replacements:

Reduce unwanted "wheel hop" that plagues the FWD MS3 and Mazda3
Solid 62A durometer bushings
Recover torque lost in the drivetrain
Billet aluminum is aesthetically very pleasing in the engine bay
Minimize drivetrain lash
Must have for all MS3's
Bolt-on installation and does not require the motor to be removed or supported

Excellent Upgrade	January 14, 2010
Reviewer: MHofmann from Malvern, PA United States

I replaced the rear motor mount on my 2009 Mazdaspeed 3 with the "Street" version of this part and the difference is night and day. Shifts are much smoother and the whole car feels more solid in general. Very minimal additional vibrations at idle and I am still in the break-in period. I had the work done at a garage and they finished in less than 20 minutes. You we be appalled at what the stock motor mount looks like, even on the 09s, which are supposed to be revised. Highly recommended.

Too good to be true but it actually is good	December 16, 2009
Reviewer: shahin MT from Ottawa, ON Canada

i have driven 300km on it so far but 200km of those k's my wheels were sniping, since its winter here. I work at a garage so i changed the mount in 20 mins using a joist and power tools. Anyway the mount definitely worth the wait and money. Wheel hop is 80% eliminated. There is no extra vibration (on street version) even in the -30c weather that i live in. Oddly enough the exhaust tone has noticeably got a deeper tone at low rpm, full throttle situations (i cant figure out why).

Awesome!	November 19, 2009
Reviewer: Bridger Henriksen from Lindon, UT United States

I was surprised at the difference it made... Also I was surprised at how weak and poorly designed the stock mount was. Looks like they used the same one from a regular 3? Anyhow I would for sure recommend this mount. Eliminated wheel hop, shifting is soo much nicer/easier and more solid. No more drivetrain backlash. A very good investment....

First impressions	November 12, 2009
Reviewer: Jeremy Evans from Ovid, NY United States

I just installed my rear mount and the install could not have gone smoothe, I had the car on the lift with the mount installed in 40minutes. You will need a breaker bar or a pretty long socket handle for those bolt thought there torqed down good and tight. I have only done a little test drive on it so far and there is some vibs but its much softer than I thought it would be I have the 62d street bushing I would deff recomend this mount for light to moderately modified cars.

Streetunit Motor Mount	November 2, 2009
Reviewer: Todd Briggs from North Richland Hills, TX United States

Just installed the rear mount. So far, smoother shifts which I've been looking for since I bought the car. Nice product, well built, and easy enough install.
