Tools Needed:


Safe means of lifting and supporting the vehicle: jack and jack stands, wheel ramps, or lift.

Torque Wrench

Socket wrench or breaker bar, 3/8" and/or 1/4"

18mm socket

16mm socket

15mm socket 

15mm deep socket

10mm socket

10mm deep socket

8mm socket

18mm open end wrench

Long and Medium socket extensions 


Components supplied should include:

1x TMM base

1x TMM bushing carrier

1x TMM top

1x Machined spacer

1x 16mm long bolt 

1x 18mm locknut

2x 15mm long bolts 

2x 15mm short bolts

2x 15mm locknuts 

Begin by partially assembling the Damond Motorsports TMM first.

Assemble the bushing carrier into the base of the mount, with the extended machined lip of the carrier facing the flat side of the TMM base. Clearances are tight, so gently press the carrier into the base by using a soft clean surface, till the holes line up on both sides for the bolts to go through:

Take the supplied 15mm bolts and nuts, and secure the base to the carrier. Be sure to put the bolts in the end shown(makes mounting the base to the transmission easier) Ensure the bushing carrier is flat in the base, pressed all the way down and not at an angle, and tighten the bolts/nuts to 45ft/lbs.

Now the mount is partially assembled and able to go into your Focus ST.


(CAUTION: allow the vehicle to cool down fully before attempting any work)

Begin by properly supporting the vehicle in the air using stands, ramps, or a lift. 

Remove the 3 x T30 screws attaching the front air deflector.

Remove the 8 x T30 screws attaching the undertray, and remove the undertray.

Lower the vehicle to the ground. And position a jack with a soft pad or block off wood under this lip on the transmission. LIGHTLY support the weight of the transmission with the jack.


Remove the battery cover and disconnect the battery terminal connections(10mm). 

Next is to remove the intake, if you have an aftermarket intake, refer to the manufacture's install and removal procedure. For the stock intake, begin with un-clipping the MAF sensor connector, from the sensor and remove the wire stay from the air box. Un-secure the intake air guide strap. Loosen the hose clamp on the J-boot(8mm), and remove the J-boot from the upper intake tube. Remove the air box assembly by pulling upward with slight force, be cautious of surrounding components and tubing.

Next remove the battery and battery box. Remove the tie-down(10mm deep socket), and slide the front cover upward to un-attach it from the box. While pushing the front cover down, remove the battery. 

Remove the battery box from the vehicle(3x 10mm bolts)

Now we have access to the factory transmission mount assembly. 

Remove the connector from the battery support by sliding it forward off the clip, and un-secure the wire clip from the battery support. 

Remove the 4x 15mm nuts securing the top of the mount and battery support to the frame, and remove the battery support. Next remove the 18mm bolt securing the transmission mount together, and remove the top of the mount. NOTE: the engine may shift while removing this bolt, be sure the jack is supporting the transmission. 

Remove the 3x 15mm bolts securing the base of the mount to the transmission, and remove the base(you may have to lower the transmission slightly while on the jack to gain better access to remove the forward most bolt) 

Place the supplied spacer on the forward most transmission mounting point.

Carefully place the Damond Motorsports TMM base into place, and ensure the spacers is still in the correct placement. Install the base to the transmission with the 2x provided 15mm bolts, and reusing one of the factory bolts on the forward most hole(blue loctite recommended). Tighten the bolts first by hand, then to 55lbs/ft(75Nm) NOTE: you may have to lower the transmission slightly while on the jack to gain better access to remove the forward most bolt.

Now put the TMM top piece into place. While re-positioning the height of the engine with the jack, align the top piece with the bushing carrier. Install the provided 16mm bolt and 18mm nut. Tighten to 70lbs/ft(95Nm)

Re-install the battery support, and tighten the 4x 15mm nuts to 40lbs/ft(55Nm).

Re-install the battery box, battery, intake, as removed earlier. Once all is done and the connectors are in-place, re-connect the battery terminals. 

Lower the vehicle if supported, and start the engine. Go for a short test drive to ensure the mount is installed properly. There may be added NVH after installing the mount, and the NVH should settle down a bit once some miles are on the mount. We recommend checking the TQ of all the bolts/nuts at 500 miles.  

Congrats! You have finished the DM TMM install. We hope you enjoy all our mount has to offer.
