Description

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.

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.

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
front-pipe-exhaust-next-27won-rear-engine-mount

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.

Got the 27won rear motor mount 90a, thanks Dalas for shipping it and it came a day before it was expected. As for the first feel, I love it! Brings back memories of when I started to learn to drive stick shift in a 1970 Beetle back when I was a teenager, I always love that aggressive feel of the car and still do now. At first it seemed that it changed the exhaust note but that's not the case, it's just the NVH of the mount that caused an increase in the cabin making it seem that the exhaust is louder. The RPM range of 1k to 2k seems a little loud even at low throttle and to some it will be annoying but I personally don't mind it since it makes me feel more connected to the car and that's exactly what I wanted for the car. Shifting feels better, I use to feel the engine going back and forth during gear changes but it's mostly gone now. I'm in PR so the roads aren't the smoothest but the wheel hop is basically gone. Fast forwarding after 500 miles, the cars NVH isn't as "bad" as it was at the beginning, it still has an "annoying" NVH between 1k to 2k RPM but that's only if you are somewhat lugging it which gets worse if you seriously lug the car. The good thing about that NVH in that range is that it makes you a better driver and reminds you to treat the car with better care. In summary, I have no regrets on going for the higher cost of the RMM for 27won, it's exactly what I wanted, I love it and am happy it was my first performance/support MOD I did to the car. I do plan to get the full product list for 27won. Odds are I am going to upgrade the clutch next to finally add more power.
I believe this is of the most overlooked performance mods out there, the OEM RMM always has a rubber band feel on the pedal and so much power is lost there. Now the car reacts much quicker to the pedal and this mod with a tune should be the first on everyone's list if power is what you are looking for

i got 27Won 70a because mine is a CVT and it was loud at first about 1200-1400 RPMs but after i went to another shop to re-torque it, (after 500km) the NVH is perfectly acceptable. ! since went for a 2000km road trip with no problems. Been out of the country and now finally back to my Civic. Cant wait to bring it for another road trip next month!
This was my first ever mod to my 10th gen civic (yay 27won!). Installation should have been 10 minutes, i made it 30 by being stupid, so don't be like me. At first, the NVH was jarring, and even became too much. I pushed through it though, and after about 500 miles, it broke in, the NVH is hardly noticeable, yet the performance of the part remains. From the packaging, to the install, to the benefit, 27 Won, you nailed it all!
Very happy with the street version — huge difference — car doesn’t shake as bad as everyone made it sound
Went with the 90A. What a great buy! The sound difference everyone is saying is too loud is honestly not bad at all. I've driven it long enough now to the point it only gets loud when you really get on it! Sounds great in my opinion! I would recommend it for sure!
Legit high-quality product. Feels like I'm driving a different car!! Fast shipping. Lots of extra swag in the box. Can't wait until more of your fk8 parts are in stock!!
Very happy with the street version. The NVH is very minimal and it’s only got 600 miles on it. The traction in 1st and 2nd is so much better. A must have mod for the FK8.
Had it for around 3 month and I love it.
Really eliminates spin in 1 and 2nd gear. You really can feel car much more better.
Highly recommend if you have car tuned makes car even more fun!
Hugh shoutout to Vlad for answering my questions and helping me to make a decision.
So I went the 90A billet mount. Only took 30mins to install. Super easy process, only tedious thing was that the front pipe wouldn’t allow the engine side bolt to go into place (which is no fault to 27Won), which wasn’t a big issue and I easily overcame it. Upon first start up a smile immediately lit up my face as I felt the car rumble. I love the feel of the pedals vibrating. I immediately noticed shifting was way smoother, and that there was no more annoying “rocking” that you would get with the stock mount. The exhaust tone inside the cabin sounds so much better (and I’m still on a stock exhaust set up). It’s a much more analog driving experience which I find refreshing. During some RPM ranges I find the NVH to be a little on the rough side, but I know that the mount still hasn’t been broken in yet. I highly recommend this mount. If you’re on the fence about this mount, the cast 70A mount from 27Won, or any other mount, I’d just send it and go with this one. 27Won knocked it out of the park yet again.
I purchased both the street and the race to see what I’d like or prefer. Or switch if I wanted to hit the track or daily. Great quality . I’m overall very happy
