In the midst of power upgrades becoming more prevalent; it is easy to focus on horsepower and torque figures. However, your numbers don’t mean much if you can’t get the power to the ground effectively.

Enter the Rear Motor Mount…the performance part you didn’t know you needed.

100% of the power your Honda Civics' engine creates must be applied to the axles/wheels/tires to get them rolling and your Civic moving; but what holds the engine in place? The rear engine mount (along with the other two mounts) have the demanding job of keeping the engine in your Civic SI in-place. Unfortunately, the OE engine mount quickly loses effectiveness as the engine power output increases.

If you find yourself fighting for traction and would like to improve throttle response then look no further, the 27WON Performance Rear Engine Mount is the performance upgrade just for you.

27won dare subheadline

27won redefine design subheadline

Compared to OE and other options on the market you may notice something is missing…or is it? With our design less is more; which is why our mount utilizes only one polyurethane isolated mounting point.

The mounting point between engine and RMM has a primary motion and secondary motion.

  • Primary = rotational
  • Secondary = up/down

  • The polyurethane mounting point on the engine reduces the primary rotational movement of the engine while still allowing a small amount of movement due to the polyurethane compressing.

    The rigid mounting point connected to the chassis sub-frame eliminates the up/down motion that the engine follows while the engine rotates. This eliminates associated secondary vibration and thus reduces NVH. Check out the blogs below for more details.

27won design strength subheadline

In an effort to reduce weight and maintain strength, the 27WON Performance RMM utilizes an “I-Beam” style design (very similar to high performance connecting rods) to connect the two mounting points. This design provides a reduction in weight without a significant sacrifice in tensile and compressive strength. The weight savings add up to ~1/2 lb vs OE.

27won durometer hardness subheadline

A noticeable bump up in performance (street) or leave it all on the track (race). The 27WON engine mount is available with 2 options for durometer hardness so you can select a mount that best suits your driving profile. Our 70A street gives a big drop in torque steer while being more civil in regards to NVH as compared to our 90A race. Our 90A race mount is for for those who put outright performance over comfort and can accept the extra NVH that gives them maximum performance.

  • Removal of aftermarket front pipes required for install
  • Motor oil can degrade and cause premature wear on certain components such as the Polyurethane bushings found in Rear Motor Mounts. Please be advised that if you have an oil leak present, your Rear Motor Mounts durability and longevity may be impacted if oil gets on these parts. In particular, watch for valve cover leaks

high quality materials subheadline

The steel sleeve within the polyurethane pucks is manufactured from 303 stainless steel for strength and corrosion resistance. The twin poly bushings are custom molded from a proprietary polyurethane blend. This material is chosen because it offers excellent performance in dynamic loading, shock absorption, and water environment, the exact conditions your engine mount will be subjected to.

27won billet or cast subheadline

The body of the 27WON Race RMM is manufactured from two types of material depending on your choice. 6061-T6 billet aluminum for superior strength and weight or die-cast aluminum for a more budget friendly version. Both versions utilize our same CAD design to ensure a mount that will perform for your 10th gen Honda Civic.

NVH subheadline

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. OE engineers and designers spend countless hours reducing/eliminating NVH from vehicles, however, this sometimes comes with a compromise in performance and vehicle feedback. Not all NVH is created equal, an OE designer may consider turbo noise to be unwanted NVH, whereas a performance enthusiast may consider it a desired sound.

At 27WON when designing performance parts that may affect the vehicles 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, intake systems, 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.

Installing Your Performance Rear Engine Mount

Waited for the 70A and couldn't be happier! Fitment was fantastic, and install process was simple! Do be advised, if you have the 27WON exhaust for the FK8 you WILL need to remove the front pipe and/or pull it out of the way to install this!
Great product very well built. Totally changes the experience driving the car, you’re a lot more connected. vibrations and noise are rough at first but give it 500 miles it’ll smoothen out.
Ive had the mount on for a few hundred km and so far I'm loving it!
Install was super easy and its totally upgraded how the car shifts. I found before the mount that so many of the shifts were sloppy and jerky like they were not ever in the same place no mater how hard I tried to shift smoothly, now they are much more consistent.
Way better!
Its a little rough starting into 1st gear from a complete stop but im sure its just the break in period.
And this coupe of mine souds like a race car now! Friggin game changer of a mount! I wish I had got it earlier! As now summer is close to an end and I want to be able to enjoy it more.

Got the engine mount among some other stuff and can't find a bad thing to say. From the costumer service, to the delivery times to the product it self, not only does the job and does it good, also it's pretty and with amazing attentiont to detail (in a mod that 99% of the time no one it's gonna see)

Realy a game changer... Its day and night very good quality product. Thx to the team
Everything from the package, through the product itself and to the installation instruction is wonderful. The NVH is noticeable, yes. You can't miss it. But as a driver you connected to the car much better and the power you getting is consistent without any WheelHop. Really love it!
Best best inversion ever I don’t have to say nothing just buy it omg !!
Hands down the best value upgrade I’ve done. I love the added noise and vibration—it’s just enough and now I can hear my engine talking to me!
I was hesitant on getting this because I didn't know how bad it would vibrate. Going forward I decided if i was going to get a test motor mount I was going to get the most agressive one i could find. Why? Cause Tim Allen growl. Got the beefiest one i could find and I have been wanting to try 27WON products for so long now. Installed it a couple days ago and about crapped for how much vibrations their were but honestly I love it. It sounds so nice and to get feedback from the car is absolutely fantastic I every way. Amazing product amazing staff. I hope to see this company do more amazing things in the car scene cause they absolutely deserve it. Well done all of 27WON.
I absolutely love this motor mount in my SI. The car feels more responsive and shifts are more crisp. More importantly it lets you actually feel and hear what the car is doing. It’s not for everyone, but I really like the increase in NVH. I just got back from an 8 hour road trip in the car with two friends who could care less about cars, and neither of them found it too loud or uncomfortable. This is a must have if you want more feedback and a more raw driving experience.
