Description

As both horsepower and torque increase on your late model turbocharged Civic or Integra, the battle for traction - to get that power to the pavement - becomes increasingly difficult.

All the power your 11th gen Honda Civic generates is sent through the transaxle, wheels, and tires to get the car rolling forward. The rear engine mount (RMM) along with the two side mounts helps keep the engine in the right place while also providing a smooth and comfortable ride. While the stock mount is okay at OEM power levels, the amount of engine movement the OEM mounts allow becomes undesirable with the extra juice that comes with power upgrades. This is just as evident in the 5th generation Acura Integra.

Upgrading to an aftermarket RMM is a great way to reduce wheel hop (the tendency for the wheels to lift off the ground under hard acceleration and driving) and thus improve traction. Power is worthless if you can't get it to the ground and the 27WON RMM is the solution.

The key to the 27WON RMM is the use of only one polyurethane mounting point versus the typical two. This may seem counter intuitive to what you are familiar with, but this is not without reason.

The mounting location of the motor mount has a primary motion and secondary motion.

  • Primary = rotational
  • Secondary = up/down
  • The poly mounting point on the engine side reduces the primary rotational movement of the engine while still allowing some amount of movement due to the polyurethane compressing under load.

    The fixed mounting spot connected to the sub-frame gets rid of the up/down motion that the engine follows while the motor rotates. This gets rid of the associated secondary vibration and thus reduces noise, vibration, and harshness. Check out the blog below from our 10th gen development for more details.

    In designing a new mount for the 11th gen we evaluated the materials used in its construction. For the metal collar we went with a 303 stainless steel sleeve due to its high corrosion resistance. The body is crafted from 6061 Aluminum for strength and integrity.

Anywhere in the build-out of your Civic or Integra that we can reduce weight we do. Our 11th gen RMM is both strong and light utilizing an I-Beam construction. This is a design feature you see in high-performance connecting rods. Our billet design increases strength without adding unnecessary weight under your ride. Compared to OEM, the 27WON unit shaves off 8 ounces.

Civic Si, Acura Integra A-spec, and other manual transmission owners have the choice to pick from 70a Street or 90a Race polyurethane for their RMM. The 70a Street is the perfect compromise of on road performance with slightly increased NVH. For those wanting out-right traction with zero wheel hop and can give up some comfort, the 90a race offers the best performance and is the choice for you. With either option, you are going to see lap times go down as your car grips.


durometer for civic subheadline

For our 2022 Civic EX equipped with a CVT, we tested many different polyurethane durometers. We recommend either our 60A or 70A hardness options for CVT equipped models.

  • 60A for those that mostly drive highway
  • 70A for those that mostly do city driving

This is also the suggestion for CVT equipped Integras. The benefits of an upgraded RMM come with subtle increases in NVH. We've been able to optimize NVH for the two scenarios described above and we believe the trade-offs are worth the performance benefits.


NVH subheadline
engine-mount-rear-under-honda-civic-2022-ex

Noise, Vibration, & Harshness (NVH) is an evaluation of the various irritants that can be transmitted through the vehicle into the cabin and directly to the driver and passengers. OEM engineers and designers spend countless hours reducing/eliminating NVH from vehicles, however, this sometimes comes with a compromise in performance and driver feedback. Not all NVH is created equal, a OEM designer may consider exhaust noise to be unwanted NVH, whereas a performance enthusiast may consider it the desired sound.

At 27WON when designing performance parts that may affect the vehicle's NVH we strive to find the right balance of performance improvement and NVH increase. Ideally, we are able to create a performance part that does not affect NVH, but that is not always the case. Examples are exhaust systems, clutch kits, engine mounts, suspension components…etc.

With the addition of a 27WON performance engine mount increased NVH will be an inherent part of the upgrade. While we do our absolute best to deliver a mount that works great and feels amazing some customers may find the higher levels of NVH to be too great. It is our guarantee that 100% of customers will love this mount. If for any reason you have any concerns with the mount simply reach out to us and our team will be sure to find a solution that works for you.

Purchased the race version. "NVH" is crazy nuts in the car. You get tons of low RPM vibration (2000-2600) to the point where it tickles your behind. Huge trade of when it comes to comfort over performance. Just tossed ALL the cars comfort straight out the window with this mod. That being said, it does what it's supposed to do. More power to ground quicker. I just wish the power difference was as noticeable as the vibrations. I try to keep my mods low profile so nobody notices but you can't hide this mod from nobody!!
What can you expect from 27WON? I've been testing this rear motor mount for almost two weeks. I got a 70a street version. Let me tell you something. The car feels fantastic, more fun to drive, and torque is right there when you need it. The vibration is a little bit, and nothing to worry. Also! The box!! OMG, that box is unique, lol. I reuse the box and put my Allen keys inside. https://youtu.be/0yRaBJDhtBc video installation
I had the street version of this RMM installed on my 2017 sport hatch cvt. Install was a breeze as long as you have the necessary tools and jack stands for safety. First thing that I noticed after I installed this was a better connection of the engine to the chassis especially during acceleration. N/V/H is tolerable and it is beginning to be even more tolerable after being broken in. Such a small part but has big benefits.
While not officially verified, 27WON said the 11th gen RMM should fit the 2.0L Civics and I can confirm that. I have the 72a mount for the 6MT Hatch. With the RMM installed it almost felt like an entirely different car! Noise is I'd say comparable to having an aftermarket muffler, but where you get a lot of change in NVH is vibration. I got used to it real quick and do prefer it much more as I feel more connected with the car. Shifts are easier to get smooth now, throttle response is substantially better, and I would say there is more usable RPM in the lower range, like when starting from a stop. Overall the car feels so much more powerful. Would definitely recommend as one of the first mods to do if you plan on releasing more of the sportiness of the Civic, regardless of if you are going to do heavy HP adders or not.
