Shock Tower Brace Installation Instructions
For Cobalt in particular but equally useful for RoadsterSport & Cusco

2016+ Mazda Miata

If your MX5 did not come with a shock tower brace from the factory, a cowl reinforcement
plate, part number 910-891, must be installed to fit this strut bar. Directions to install the
cowl reinforcement plate can be found at the end of these instructions.

Parts may vary slightly from pics.
Tools required:
• Ratchet
• Torque wrench
• Sockets: 10mm, 10mm deep,14mm
• Universal joint
• 10" Extension
• 10mm wrench
• Needle nose pliers
• Slip joint pliers
• Rags

Removal of the Factory Shock Brace
1) Disconnect the battery.
2) Remove the front section of the sound tube attached to the intake at the front of the engine bay. Remove
the two outside hose clamps, and the 10mm bolt securing the center of the tube. Figure 2.

3) Move the sound tube chamber out of the way by removing the 10mm bolt securing it to the outside
edge of the engine compartment, and then lifting straight up to separate it from the shock tower plate.

4) Remove the factory shock brace. Unfasten the six nuts securing the brace to the shock tower plates
and firewall. Pull out the rear section of the brace before the two side sections. Figure 4.

5) Move the EVP control unit fastened to the passenger side shock tower plate. Use needle nose pliers to
release the backs of the clips holding the wiring from the control unit. Unfasten the two 10mm bolts holding
the control unit bracket to the shock tower, and move it out of the way. The large connector on top of the
control unit does not need to be disconnected. Figure 5.

6) Remove the passenger side shock tower plate by unfastening the three 14mm nuts, and lifting it off of
the studs. Figure 6.

7) Move the ecu attached to the driver’s side shock tower plate. There are three 10mm bolts in total. Two
bolts are located on top connecting the ecu bracket to the shock tower plate, and the third is located at
the bottom of the ecu. The bottom bolt needs a 10 inch extension and universal joint to unfasten. Gently
move the ecu off the studs of the shock tower plate and place a rag between the ecu bracket and the
shock tower to protect the paint. Do not disconnect the ecu from the wiring harness. Figure 7.

8) Remove the driver’s side shock tower plate by removing the three 14mm nuts.

9) Clean the shock tower surfaces where the new brace will be mounted. Any debris left over may damage the paint.

10) Place the new shock tower brace onto the same eight mounting studs as the factory shock tower brace. Figure 10.

11) Using the nuts that were removed earlier, secure the new brace. Torque the six shock tower nuts to 37-43
ft-lbs, and the two firewall nuts to 12-19 ft-lbs.

12) Bolt the EVP control unit on the passenger side of the vehicle to the shock brace using the two included
M6x35 bolts, washers, and nuts.

13) Remove the D shaped clip from its line and bushing located near the EVP control unit. Flip it upside down
and reinstall it to fit the hole in the bracket attached to the control unit. The rubber bushing underneath
will need to be moved up. When everything is in place, install the clip into the bracket. Figure 13.

14) On the driver’s side of the vehicle, mount the ecu back in its original location. Use the original bolt
to secure the lower mount of the ecu, and the two M6x25 bolts, washers, and nuts to secure the top two
mounting holes. Figure 14.

15) Mount the sound tube chamber into place on the driver’s side. Use the original bolt to secure the
outside mount, and the included M6x40 bolt, 20mm washer, and nut to install the other side to the shock
brace. Figure 15.

16) Make a connector using the small stainless steel pipe and rubber hose included in the kit. Push the pipe
into the hose until approximately 3/4” of the pipe is sticking out, and use one of the included hose
clamps to secure them together. Figure 15.

17) Mount the rubber side of the connector onto the sound tube chamber, and secure it with the second
clamp from the kit.

18) Using the original bolt, install the long end of the included bracket where the center of the sound tube
was originally mounted. Figure 18.

19) Rotate the portion of the sound tube that connects to the intake 180 degrees, so that the bottom is now
facing up. Figure 19.
