Introduction

In this installation guide we have provided step by step instructions to remove the OEM rear motor mount and install the 27WON Performance Rear Motor Mount.

Advisory:

  • Working under the vehicle requires a safe and sturdy location for the vehicle to sit on jackstands.
  • The engine & exhaust can be hot after recent vehicle operation. Allow the vehicle to cool or use a fan to cool before working on the vehicle.

    • 27WON Performance has worked hard to design a Performance RMM that performs great and minimizes unwanted harshness to the vehicle passenger compartment, however Performance Engine Mounts will increase the NVH (Noise, Vibration, Harshness) of the vehicle over OEM levels.

  2. Hello and welcome to the 27WON Rear Motor Mount install guide. Through out this guide we have included photos of both our Billet RMM and our Cast RMM to aid in your install. We have done this for your convenience but just so you are aware the install will be the same no matter which mount you have purchased. 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. 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.

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.

    • 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 take care of any issues for you.

  3. Raise the vehicle and support with jackstands in the OE recommended locations
    • Raise the vehicle and support with jackstands in the OE recommended locations

    • Use a flathead screwdriver to remove the six (6) click-lock fasteners circled in red

    • Use 5mm Allen wrench to remove the two (2) bolts shown circled in orange

    • Slide the metal undertray section towards the rear of the car off the plastic retention clips (shown with yellow arrows), then remove from vehicle

    • Use 10mm socket & ratchet to remove the three (3) bolts shown circled in green

    • Use a flathead screwdriver to remove the two (2) plastic push-clips circled in blue

  4. The OE RMM is shown with the red square
    • The OE RMM is shown with the red square

    • Through the installation instructions we will reference each end of the RMM, below is the identification:

    • Shown with the orange circle is the chassis mounting end of the RMM

    • Shown with the yellow circle is the engine mounting end of the RMM

  5. Using a 17mm socket and breaker bar, loosen the chassis end RMM bolt indicated with orange circle Unthread and remove the 17mm chassis end RMM bolt
    • Using a 17mm socket and breaker bar, loosen the chassis end RMM bolt indicated with orange circle

    • Unthread and remove the 17mm chassis end RMM bolt

    • The plastic undertray will need to be pulled downward to provide clearance - the plastic can flex enough to provide clearance without issue

  6. Using a 19mm socket and breaker bar, loosen the engine end RMM bolt indicated with red circle Unthread the 19mm engine end RMM bolt
    • Using a 19mm socket and breaker bar, loosen the engine end RMM bolt indicated with red circle

    • Unthread the 19mm engine end RMM bolt

    • Due to exhaust (front-pipe) location, the engine end RMM bolt will only unthread to this extent - this is not an issue for RMM removal

    • At this point the engine end of the RMM should be able to move vertically down a small amount. If the bolt cannot be completely unthreaded, then the front pipe (orange arrow) may need to be loosened and moved out of the way.

    • With some aftermarket front-pipes, the diameter of the front-pipe may not allow the bolt to be unthreaded fully. If the bolt cannot be completely unthreaded, the front pipe may need to be moved

  7. For improved clarity we have provided an image of the Civic 1.5L MT transmission and the Civic Type-R transmission To remove/install the RMM, the transmission must be rotated forward with pry bar to provide extra clearance

  14. A performance rear motor mount by design reduces engine movement to mitigate unwanted wheel hop, slow throttle response, and torque steer - the by-product of this is increased NVH (Noise, Vibration, Harshness) that is transmitted to the vehicle cabin Like most performance modifications, understanding the changes to the vehicle caused by the modification is critical.  In these instructions we want to advise you on the expected changes  :
    • A performance rear motor mount by design reduces engine movement to mitigate unwanted wheel hop, slow throttle response, and torque steer - the by-product of this is increased NVH (Noise, Vibration, Harshness) that is transmitted to the vehicle cabin

    • Like most performance modifications, understanding the changes to the vehicle caused by the modification is critical. In these instructions we want to advise you on the expected changes :

    • Polyurethane has a "break-in" period, we advise that you drive with the RMM for a couple weeks to let the RMM poly settle in. We are confident that you will love the new performance benefits

    • Increased vibration to the vehicle cabin is to be expected, there are some driving habit changes that will reduce the added vibration: try not to to "lug" the engine at low RPM. High engine load (hard throttle) at low RPM may exaggerate the vibration

    • The temperature of the poly will affect its stiffness, cold mornings may transmit more vibration. This will disappear as the polyurethane warms up with the engine heat

    • We want every customer totally satisfied with our RMM. Your personal satisfaction with the 27WON RMM is very important to us. If you have questions or concerns please give us a call at 571-271-0271.
