Installing the strut tower brace requires some careful measuring, since it doesnt bolt to any factory mounting points (all mounting holes must be drilled). Stuber bolted together the entire three-piece strut tower assembly, attached its brackets, laid it over the engine bay, and measured to make sure it was centered. Note that the engine isnt centered in the engine compartment, so dont use the plenum as a reference. Once the bar was centered, Stuber drilled two holes for each strut tower bracket, and two holes in the cowl to attach the braces. The car was lowered to the ground to pre-load the chassis, and we made sure none of the bracing was touching the hood before torquing the entire assembly to spec.
