Radium Engineering 2015+ Subaru WRX/STI Master Cylinder Brace

Radium Engineering designed the 2015+ Subaru WRX/STI Master Cylinder Brace as a purpose-built solution that limits master-cylinder and firewall movement under hard braking to improve pedal consistency. The application-specific brace supports the master cylinder without changing the hydraulic system, making it a straightforward chassis-side upgrade for a firmer, more repeatable pedal feel.

For Subaru WRX/STI, it is intended to integrate with the vehicle-specific layout rather than serve as a universal substitute. Use only on the listed chassis and set brace preload according to Radium’s installation procedure.
