27WON is working hard on upgrades for the 11th generation Honda Civic. Our 2022 EX is being taken apart on the daily. We recently released our front strut bar for the 11th gen. We have a couple of other parts racing to take the 2nd release spot. We’d like to share one of those with you today!

The OEM Rear Motor Mount (aka RMM) found in your 11th Gen Honda Civic has a major effect on the feel of your car. Your RMM affects your Civics' throttle response, wheel hop, and traction. Replacing the RMM is a popular early mod and one we recommend.

But first let's briefly go over what a Rear Motor Mount is, how the OEM one works, and why you might want to replace it.

Above, we see the Honda design found on the 11th gen civic. The design and construction of the OEM rear motor mount feature a rigid body manufactured from a hard plastic material with two ends designed to hold an elastic damping material and a rigid pin or sleeve for fastening. These huge elastic dampeners smooth and soften your ride at the cost of numbing throttle response, reducing traction, and increasing wheel hop. The engines in modern cars move and pivot in the engine bay A LOT, and the Honda Civic is no exception.

Now you know what the OEM RMM is and how it works, let's get into the design of the 27WON 11th gen RMM.

Building on the trusty reliable design of our 10th Gen RMM, we have transformed it to fit the 11th gen Honda Civic! Below you can see how the 11th gen RMM features the same flex of our 10th gen RMM while meeting the new more compact shape necessary to fit in the 11th gen Honda Civic.

Notice that similar to the 10th gen Civic RMM, we have eliminated the big bushing on the chassis side and replaced it with a stiff hard mount. This is done for a very specific reason to increase feedback and reduce noise, vibration & harshness (nvh).

Oh and did I mention… Billet Aluminum!!!

We are working through our prototype phase so we have not settled on the ideal stiffness (durometer) of the bushing just yet. We suspect it will likely be between 60A to 70A for the CVT transmission as this usually provides the best balance of driver feedback and NVH (noise, vibration, harshness). The 6-speed manual will likely land in the 70A to 90A range as the manual transmission generates less NVH.

WE WANT TO HEAR FROM YOU! Is there anything you want to see done differently compared to the 10th gen RMM? Think there should be a cast version? Do you want to see a new etch or engraving? Got a suggestion, drop it in the comments below! We want to hear them!

That's just one way we REDEFINE the Aftermarket.
