Description
 
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

Black Out Powdercoating Option

huge improvement after install May 30, 2009
Reviewer: Joshua  I. from Orlando, FL United States  
I have been waiting for the whole mount kit from SU but I got this one before the side mounts, let me tell you! This mount made my car perform like new, NO traction loss! The power is put firmly to the ground! I also have a cracked cylinder head mount bushing, so this mount is picking up the rest of the slack...til I get the other mounts. Streetunit you guys rule! And the fact that you're based out of FL is a huge plus! Thanks again for everything!

Solid piece May 13, 2009
Reviewer: Chris Jawornicki from Halifax, NS Canada  
I'd like to start by yet again saying how great the guys at SU are with customer service.

Everyone's already said it, super easy install, needed a 17mm & 19mm socket, and my jack, 30 min later you have a new mount.

First impressions, yes there is a slight vibration at idle BUT only sometimes, and when it is there it is very slight. Although wheel hop is greatly diminished, I found that there is still a little bit left. But I would say it is due to the Potenzas which are reluctant to just spin. But hard launches and spirited starts now feel good. Great purchase.

Another SU winner. A great "starter" upgrade! May 13, 2009
Reviewer: Gabe from Honolulu, HI  
Seems daunting to any newbie to try to replace a motor mount, so stop right there: IT'S A SUPER EASY INSTALL!!  You got jack stands??  A decent socket wrench set?  You're ready to go in less than half an hour!!
After install and proper break in, I did notice a difference during launches/spirited starts; less clunk, more go!  I have NO VIBRATION issues that I can find, before and after installation feel the same.  
Great job Street Unit!! I can't wait to match this up with the other SU mounts!
