Perrin Master Cylinder Brace Black 2008-2014 STI / 2007-2009 Legacy / 2007-2009 Outback XT | CNC Machined Aluminum & Steel | Brake Pedal Feedback Enhancement
Overview
The Perrin Master Cylinder Brace is designed to eliminate firewall flex by securely bracing the master cylinder against the shock tower. This upgrade is ideal for Subaru WRX STI, Legacy, and Outback XT owners who demand precise and consistent brake pedal feedback. Whether you're slowing down for a stop sign or pushing your vehicle harder on spirited drives, this brace ensures you feel a solid, direct connection through the brake pedal every time.
Engineered with a combination of CNC machined 6061 aluminum and CNC formed steel, the brace offers superior stiffness and lightweight strength compared to traditional welded steel designs. Its unique triangulated mounting system bolts to three different surfaces around the shock tower, significantly reducing flex in multiple planes. This thoughtful engineering approach not only improves braking feel but also adds a clean, OEM+ aesthetic to your engine bay with a sleek anodized black finish and laser-engraved Perrin logo.
For Subaru enthusiasts, this master cylinder brace translates to enhanced brake control and confidence behind the wheel. The reduction in pedal flex means more immediate response and better modulation, which is especially valuable during aggressive driving or track days. This part perfectly complements other Perrin performance upgrades, making it a practical and visually appealing addition to your Subaru’s braking system.
