Brake Cylinder Stopper, designed to stablize the brake master cylinder on your 2015-up Subaru WRX/STI (LHD). Upon hard braking, the sheet metal of the firewall to which the brake master cylinder is attached to, flexes immensely from hydraulic pressure and applied human pedal force. Works effectively with factory brake systems and or upgraded units. This modification will effectively result with improved brake feel and quicker pedal response.

Various Brake Cylinder Stoppers are also integrated with Cusco Strut Tower bars, making great performance improvements in one quick installation.

Brackets: Lightweight steel and finished in the Cusco signature blue color.

Hardware: All necessary hardware is included. No fabrication, cutting or welding necessary.

Availability: Please check to see if there is one by selecting your vehicle from the vehicle look up menus.

Installation Method: Simple bolt-on type and intended for installation behind the driver’s side shock tower and in front of the master brake cylinder.
