Perrin Master Cylinder Brace 2002-2007 WRX / 2004-2007 STI / 2004-2007 Forester XT | CNC Machined Aluminum | Brake Pedal Precision Upgrade
Overview
The Perrin Master Cylinder Brace is a precision-engineered upgrade designed to enhance braking performance for Subaru WRX (2002-2007), Subaru WRX STI (2004-2007), and Forester XT (2004-2007) models. By reinforcing the firewall area around the master cylinder, this brace eliminates flex during heavy braking, resulting in a firmer and more consistent brake pedal feel. This improvement translates directly to increased driver confidence and control, whether on the street or the track.
Crafted from CNC-machined 6061 T6 aluminum and finished with a durable black anodize coating, the brace exemplifies Perrin Performance’s commitment to quality and functional design. The direct bolt-on installation requires no drilling or cutting, ensuring a clean and secure fitment that integrates seamlessly with your Subaru’s existing chassis components. Stainless steel hardware is included to guarantee corrosion resistance and long-term durability.
For Subaru enthusiasts focused on improving brake response and pedal feel, this master cylinder brace addresses a common weak point in the braking system. By stiffening the firewall and reducing unwanted movement, it helps maintain consistent brake pressure and pedal modulation. This upgrade is especially beneficial for drivers who push their cars hard in spirited driving or track environments, where brake performance and reliability are critical.
