Help control engine deflection and get more power to the ground with Steeda's Lower Engine Mount for your 2013-2018 Focus ST 2.0L or RS 2.3L.

Our upgraded engine mount is constructed from 6061 billet aluminum and comes with two sets of different bushings.

The red soft 70 durometer bushings will greatly increase control over the factory mount while keeping smooth engine/vehicle operation.

The black stiffer 88 durometer bushings will further increase control but introduce a mild level in vibration and harshness into the vehicle.

Our mount is an easy bolt on installation that will noticeably improve launching, power delivery, and shifting feel.

Wow. What a noticeable upgrade!
After having my Focus ST for 7 years, it was time to do some upgrades/maintenance. The stock mounts were garbage. I changed all 3 mounts for the engine/transmission. The vibration is a bit of a downside, but the upside is my engine doesnt jump around upon starting the car, going over bumps, shifting hard or making turns. It actually makes the car feel TIGHT. Tighter than it was when it was brand new. Cornering is more fun then it was when I first bought the car. The upside far outweighs the downside. I am glad I upgraded!

Great mount
Mount was really easy to install I used the softer bushings as I didn’t want the harsh vibration, it’s really cool they give the option between softer and stiffer bushings if you ever wanted to switch. As far as noticeable vibration there is quite a bit but after a few hundred miles you don’t even notice it anymore and the car performs much better ! The shifting is like butter now ! I absolutely love it and should have bought sooner

HUGE improvement
Installed in my 2015 SE hatch with the dual clutch transmission to replace the old, worn out factory mount. This mount tightened everything up and actually helps get power to the ground. The car feels quicker and more responsive (as quick as an automatic N/A Focus can). As for NVH, I went from worn engine, transmission, and rear motor mounts to new factory mounts and this rear mount so I can't accurately compare to stock. Definitely recommend this mount if you're serious about performance!

Performance improvement
Installed this mount on my 2015 SE 2.0 hatch before a 1200 mile round trip journey and ill be honest the initial vibrations will be a big shock after install, but dont panic. After a few days of driving and resting to break it in, the vibrations become extremely bearable and hardly much worse than stock. But the performance improvement even with just the lesser red bushing is great. Almost no hesitation from the transmission between shifts and i probably have easily picked up a second on my 0-60 time, maybe even more..

Much less wheel hop
The driving dynamics altered by the Steeda shifter and rear motor mount truly assist with the ergonomics with smoother, crisp shifts and much less wheel hop.

No more 1--2 bang or wheel hop
Before having the rear motor mount installed driving the Focus ST as it was intended was a bit sketchy with loads of wheel hop and the infamous 1-2 gear bang. I can easily say that upgrading your rear motor mount is a must if you're serious about performance.

Wheel hop is non existent
I installed the Steeda rear motor mount. I can't feel it with the a/c on which is good and it doesn't vibrate the car apart. Plus wheel hop is like non existent now which is a huge plus. Same goes with tq steer.

Highly recommend
Put this bad boy on with the Steeda catless downpipe (no longer offered). I used the 88 durometer bushings. And yes, there is a VERY noticeable difference in NVH (Noise, Vibration and Harshness). I'm no stranger to modified vehicles and this feeling is actually very welcomed and gives you a better butt-dyno feeling of how the car is behaving. Install was a snap! To swap out the bushings, just put a good long and stout screwdriver through the center of the mount and give it a couple good whacks. That steel bushing will pop out. As a side note, make sure to have some Gojo on hand. That lubricant will get on everything your hands touch and dawn dishsoap won't even touch it. Disassembling the stock mount wasn't so bad really, and since I did this while doing the downpipe, doing this first will give a chance for the car to cool down. When you take the bolt out of the dogbone connecting it to the motor mount, do not have your hand in the vicinity. It's under tension and your hand will get injured when that bolt comes out. Installation takes a little creativity. get the mount itself into place and the holes lined up and threat the 15mm bolt for the mount through, but don't torque it down. Then, using a second person or a long breaker bar, move the engine so you can slide that bolt through the mount and dogbone. Now you can torque everything down and wrap up the install. Throttle response is instantaneous. I can feel the car in the steering wheel. This modification essentially all but eliminates lost torque to the wheels in trade for comfort. If you want more performance go with the 88 durometer, if you want more comfort go with the 70. Either way, your car is going to behave like a different animal after this is installed.
