    Master Cylinder Braces

    Improve brake pedal feel and enhance overall braking performance with a master cylinder brace from Subispeed. Our selection includes master cylinder braces designed to reinforce the connection between the master cylinder and the firewall, reducing flex and providing a more solid pedal feel. By minimizing firewall movement during hard braking, a master cylinder brace helps to eliminate pedal sponginess and improve brake pedal response. This upgrade is particularly beneficial for Subaru WRX, STI, Forester, or Crosstrek owners who participate in high-performance driving or track events. Choose from reputable brands like Perrin Performance, Cusco, and Whiteline to ensure quality construction and precise fitment. Installation is typically straightforward and requires minimal modification. Enhance the responsiveness and precision of your Subaru's braking system with a master cylinder brace from Subispeed and enjoy improved pedal feel and confidence-inspiring braking performance.
