LG Motorsports LG G5 Strut Tower Brace - Manual (Page 3)

Once the holes are drilled for the firewall plate loosely place the 10mm bolts,
washers, firewall support and nuts onto the firewall. Then you will slide over each side
mount onto the brace using the supplied 5/16” x 1.25” bolts and this will make the
template for the holes that will need to be drilled into the strut towers.
After the holes are drilled for each side mount, clean the drilled holes and bolt
into place using the supplied 5/16” hardware. The top bolt hole locations will use the
longer 1.25” bolts, while the bottom holes will use the shorter 1” bolts.

Once all holes have been drilled and located. Start by securing the firewall bolts
first then the strut tower bolts, and finally the strut tower mounts to the brace. All
hardware is nylock so no thread lock is required.
