Product Description
The PERRIN PSP-BRK-405BK Master Cylinder Brace aims to eliminate firewall flex that can make the brake pedal feel soft in Toyota, Scion, and Subaru’s FR-S, BRZ, and 86 series. Made from precision CNC-machined 6061 aluminum and finished in sleek black anodizing, this brace attaches directly between the master cylinder and the driver-side shock tower. It significantly improves brake pedal firmness and responsiveness.
This brace is easy to install with the included hardware and doesn’t require any drilling. It enhances safety by keeping the master cylinder steady during hard braking. It’s great for spirited street driving or track use, and it fits all trims of the Subaru BRZ from 2013 to 2020, the Scion FR-S from 2013 to 2016, and the Toyota 86/GR86 through 2023. Coverage is confirmed through 2023; fitting for 2024 and later models is unconfirmed at the time of this listing. Backed by a 5-year warranty, it’s a solid upgrade for drivers looking for better brake performance.
