Description
 

Street Unit Performance Billet Aluminum Rear Engine Mount
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.
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

WOW! September 8, 2012
Reviewer: Justin Holst from Goddard, KS United States  
Just installed, too easy by the way! Such a difference in driving characteristics! Shifts feel more firm, wheel hop is so small almost not noticable. As for the vibrations, there are some, but only from a dead stop low rpm 1st gear and idle with A/C on... on the highway, nothing! Would def recomend!

2 years later AND August 6, 2012
Reviewer: Sam Short from East Islip, NY United States  
It still does the job. I bought this at first because i was having probs with my synchros and thought this might solve the problem. Before it came in, my prob got worse and eventually MazdaCorp just replaced 2nd gear synchro for me cause it was "defective" @ 400 miles :/ ... While they replaced that, a bunch of parts i ordered came in, including this motor mount. I asked Mazda if they'd be cool putting it in and they were happy to do it. They knew right away and recommended it too. Needless to say once i got my car back, the car vibrated alil more at a dead stop idle. Not a whole lot more but if u had like an empy soda can in ur cup holder, you'd hear it rattle now. I don't notice it anymore, cept cans ratteling. Shifiting is better than new and still 2 years later feels great. Replace my shifter bushings next since those are rubber and crappy like the stock RMM... This is a must buy!

What vibration July 30, 2012
Reviewer: toprock from Alexandria, VA United States  
When I heard about this mount until the moment I ordered and received it, I was mentally preparing myself for the Vibration and Chatter everyone was talking about...As soon as I started my car after installation I asked..."What vibration?" I can barely feel if any vibration. Maybe that's because I didn't have my AC on...but I DID have my heater on...Anyways did a test drive and MAN 1st and 2nd are smooth like butta...did a couple hard launches...very little wheel hop now. If you like me hate the vibration(especially with A/C on) I recommend buying this product NOW during winter, so by the time Spring/Summer rolls in it will be broken in already...I feel very little if at all no vibration. Car runs smoother, I feel the power hitting the ground now. Definitely worth every dollar! BUY THIS NOW!!

No hop, better shifting and better handling July 21, 2012
Reviewer: Anonymous Person from Tamarac, FL United States  
I bought this with the SU side mounts and it was the best investment ever. Small vibration with the AC on while the car is in idle but nothing exagerating. No wheel hop and i was able to feel the true power of this MS3. I recommend this and side mounts specially since the stock motor mounts are not that durable.

No more hop, better shifting March 12, 2012
Reviewer: GMAN from Walnut Creek, CA United States  
Huge difference from stock. Stock mount just flops around under there compared to SU mount. Wheel hop is eliminated with this little jewel. Smoked em day one and it was so much better. Shifting is much crisper too. Vibration is there with the AC on for sure but it isn't too bad. The car is mean and raw already. This just makes meaner and rawer. A good performance mod for the $.
