This chassis brace from Cusco installs under the center of the car to tie together the front suspension mounting points with the center floor pan, improving chassis stiffness, precise suspension location, and steering response. Very lightweight, strong tubular aluminum design, with a gorgeous metallic blue finish.
No drilling required, but if your car has plastic under-panels those will have to be trimmed or removed for this brace set to fit.
Fits all 2008-2014 Subaru WRX and STI.
