As both horsepower and torque increase on your turbocharged Civic, 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 help 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.
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 RMMis 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 sidereduces the primary rotational movement of the enginewhile 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 themetal collar we went with a 303 stainless steel sleevedue to its high corrosion resistance. Thebody is crafted from 6061 Aluminumfor strength and integrity.
Anywhere in the build-out of your Civic 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. Ourbillet design increases strengthwithout adding unnecessary weight under your ride. Compared to OEM, the 27WON unit shaves off 8 ounces.

Civic Si and other manual transmission owners have the choice to pick from 70a Street or 90a Race polyurethane for their RMM. The70a Street is the perfect compromiseof on road performance with slightly increased NVH. For those wanting out-right traction with zero wheel hop and can give up some comfort, the90a race offers the best performanceand is the choice for you. With either option, you are going to see lap times go down as your car grips.
For our 2022 Civic EX equipped with a CVT, we tested many different polyurethane durometers.We recommend 60A level hardness for the CVTdue to its balance of increased performance without adding too much Noise Vibration Harshness (NVH).
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. Whilewe do our absolute best to deliver a mount that works great and feels amazingsome 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.

Removal of aftermarket front pipes required for install
I'm going to start with what I didn't like. 1. The gasket needs beefing up, & I feel like the 2 halves should come assembled. 2. It requires the bracket to be bent downward underneath the A/C line, if you are installing on my DE5. The entire assembly needs to be pulled forward to clear the hardlines behind the tank. 3. The Radium clamp left a leaked at the radiator connection. 4. It would be a cleaner look if the vent hose angled or pointed in a direction away feom the engine.
Now, what I like. The 2 halves give it a cleaner & more engineered appearance vs PRL my second choice. The view window is a great touch & makes a visual easy. It has a small footprint & is well built.
Overall, this is a good addition to my DE5. Injust plan on ordering service supplies in case it leaks due to my assembly. Despite my gripes, I'd still recommend it.
I genuinely cannot believe the difference this paired with the intercooler makes. You can feel the car breathing better. IATs dropped over 30%. Phearable stage 4 tune makes it come alive. Highly recommend
I’ve really been enjoying my tuner these past few days and I really never want to go back to stock. Also, when I needed my free TSP tune the support team was so quick to take care of it!
