First and foremost; THANK YOU for becoming a part of the 27WON Family. We hope to REDEFINE your experience of the aftermarket with the highest level Parts, Customer Service, Packaging, & Support

Install was performed on a 2022 Civic EX. Installation on other models may vary

Hello and welcome to the 27WON Rear Motor Mount install guide.

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

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

Locate the skidtray

Use a Philips head screwdriver to remove four (4) screws

Use a flat head screwdriver to remove four (4) half-turn screws

Gently hold the skidtray up a little bit and move it toward the rear of the car to remove the skidtray

Locate the front and rear bolts for OE rear motor mount

Grab a 3/8" ratchet, extension and a 19mm socket to remove front bolt

Use one hand to lift the frontpipe when removing the front bolt

Use the same 3/8" ratchet and a 17mm socket to remove the rear bolt as shown

Front and rear bolts different lengths so make sure you don't mix them up

Pull the motor mount down a little bit and slide the OE Motor Mount toward the front to take it out

27WON Front Pipe Shown

Remove three (3) nuts securing front pipe to down pipe using 14mm socket and ratchet

Pull front pipe off studs and rest to the side as shown

This is to allow movement of front pipe to install hardware and align mount later

The 27WON RMM was design to be installed in one orientation. Please review before proceeding to the 27WON RMM installation

Chassis End - This side of the RMM will be mounted to the chassis sub-frame. We refer to this bolt as the back one

Engine End - This side of the RMM will be mounted to the engine mounting bracket. We refer to this bolt as the front one

Engraved W Logo - This logo should face the exhaust front-pipe of the vehicle when installed

Gently slide the rear end of 27WON RMM into the bracket as shown

Make sure that the "REDEFINE" text is facing the passenger's side

You should not need to force the RMM in

Use pry bar to separate front pipe from the engine as shown

Be careful not to dent the front pipe

This will clear the head of the front bolt for install

Insert front bolt and thread by hand until resistance is felt. You will torque this bolt down in a later step

Reposition front pipe over the downpipe studs as shown

The rear bolt hole on the mount needs to be aligned with the chassis hole before inserting the last bolt

Pivot or rotate engine to align bolt hole as shown

Reinstall rear bolt and thread by hand until resistance is felt. You will torque this bolt down in a later step

This should be easy if the hole is aligned right

Use a 17mm socket and torque wrench to torque rear bolt to 65lb-ft

Use a 19mm socket and torque wrench to torque front bolt to 50lb-ft

Reinstall three (3) nuts securing front pipe to down pipe using 14mm socket and ratchet

Use a 14mm socket & torque wrench to torque each to 30-40 lb-ft

Slide the skidtray back on the car

Make sure skidtray is on the two clips in the rear

Reinstall the four (4) Philips head screws back on

Reinstall the four (4) Flat head screws back on

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.

This completes the installation of your 27WON Performance Rear Motor Mount
