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 Civic’s 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.


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.


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.


The body of the 27WON RMM is manufactured from 6061-T6 billet aluminum for superior strength and weight. The vibration isolation pucks are made from 90a polyurethane for its durability and ability to withstand high forces and heat. The steel sleeve within the polyurethane pucks is manufactured from 303 stainless steel for strength and corrosion resistance.


Noise, Vibration, & Harshness 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 system, 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.


The OEM break-down

Installing Your Performance Rear Engine Mount

Difficulty: 1/5

1/5 Difficulty




Looking to reduce wheel hop and drivetrain slop? This part should be at the top of your list! Brilliant design that achieves its goal with ease. Install is fairly simple, for me the most annoying part was having to un-bolt the frontpipe. If your are at all a racing or performance driving enthusiast, this little mod will go a long way in helping you feel more connected to the car and the road. However, do not expect the cabin experience to be like OEM. Immediately after installation, your first few drives will be rough, but it does mellow out overtime as the bushing breaks in. After break-in you will still experience vibration at low rpms and additional noise throughout the rev range. Coming from a background of multiple fully-built cars in the past with a variety of solid type mounts I knew what to expect but for those with no experience, I recommend seeking out someone local with it installed to go for a ride/test drive.
I purchased this RMM for my '18 Civic Type-R, and couldn't be happier. Install went mostly without issue (some minor percussion may have been used), and the part itself is well made and fantastic looking!

The first 500 miles were an absolute treat! Vibration was crazy while the RMM wore in, but it was a blast. It made me fall in love with the car even more. Now that it's been about 600 miles, the RMM is much more smooth. The NVH isn't much different at normal RPM, but redlining the car and hanging in the high revs can be harsh. But I love it, since I want that feedback when I'm pushing the car.

I've definitely noticed more stability from the front end since the install. Corning feels a bit more planted, and I see much less of the VSA light when launching.

Overall, a fantastic part and a requirement for a Type-R.
At first I was hesitant about getting this mount. I was orginally going to get the Hasport 62a, but found out about the gains with this product. I was very hesitant and concerned about the NVH as this is my first time experiencing a stiff motor mount. I pulled the trigger and I am not disappointed. After only 200 miles the vibrations greatly settled down, but the sound remained. The vibrations can only be felt through the steering wheel and pedals.

- Up and downshifting is much smoother
- First gear rubber band effect is gone
- Third gear doesn’t get caught when shifting from second to third
- You hear the engine and transmission sounds more
- Traction is greatly increased
- Wheel hop is nearly gone
- The throttle is so much more responsive
- Great mod for the money

- Increased vibrations can and have lead to plastic trim rattling around
- Definitely not for everyone, although it’s not as bad as some say it is
- Increases interior drone, especially with my muffler/resonator delete
- Passengers may or may not tolerate the NVH
product is awesome and well built, would recommend this RMM to anyone looking for one.
No part has been nearly as controversial as this. My wife hates it, my son and I love it. Cool part about that, is that it's MY car, lol. I've had an RSX-S with the J's Racing Dampener in the past, so I already sort of knew what to expect. What I didn't expect was how much I was actually going to now hear the actual engine (vs. intake and exhaust sounds, of course). 10th Gen's are tweaked to the point of near-complete engine numbness as far as cabin feedback, and this essentially flips that idea on its head. As a car guy, I couldn't ask for a more bang for the buck mod. Sure, you feel the vibrations, there's no getting around it. But as other reviewers have said, give it some time, as it is like getting used to a new car. I can also advise that the more mods you have on your 10th gen, the more you will appreciate this one device giving you the ability to truly put that extra power you're making TO THE GROUND. Overall, a great, affordable mod that all car enthusiasts should have on their 10th gen. I'd leave it off your wife/GF's Civic, though, If I were you...!
If you're anything like me, you will rethink your decision the first time you start up your car after the install of this motor mount. Stay the course and let the mount get broken in and your initial concerns will go away. The initial startup has a lot of noise and vibration, but after it is broken in, it's not bad at all. There is more sound and vibration than the stock mount, but it allows you to really feel and hear what is happening with the car. I just finished a 600 mile round trip with this mount and didn't find the vibration or sound to be a deal breaker. The biggest change you will notice is how smooth shifting gears will become. To me, this is a must have upgrade if you are using a short throw shifter.
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
