GrimmSpeed Brake Master Cylinder Brace for 2008-2014 Subaru Impreza, WRX, STI & 2008-2009 Legacy - GRM091029
$109.00
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits select 2008-2014 Subaru Impreza, WRX, and STI models, and 2008-2009 Subaru Legacy models.
The thin sheet metal of the Subaru firewall is prone to flexing under heavy braking, which manifests as a soft or inconsistent pedal feel as the master cylinder physically shifts. The GrimmSpeed Master Cylinder Brace (MPN: GRM091029) provides a rigid bridge between the brake master cylinder and the driver-side shock tower. By creating a mechanical stop, this brace eliminates firewall deflection, ensuring that every bit of pedal pressure is converted into braking force rather than wasted energy.
- CNC laser-cut and bent steel construction for maximum rigidity
- Durable textured black powder coat finish for corrosion resistance
- Large adjustment bolt with a high-visibility red anodized cap
- Includes all necessary high-grade mounting hardware for a bolt-on installation
- Reduces firewall flex to provide a firm, tactile brake pedal feel
- Manufacturer Part Number: GRM091029
