This chassis brace from Cusco installs under the center of the car to tie together the rear suspension mounting points with the rear floor pan, improving chassis stiffness, suspension location, and steering response. Very lightweight, strong tubular aluminum design, with a gorgeous metallic blue finish.

Installation may require drilling or cutting, depending on car modifications. Not that this part is not going to be compatible with most front-crossmember horn mounts, nor with most front-mounted intercoolers.

Fits all 2008-2014 Subaru WRX and STI.
