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.
Figure 3. 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.
