Overview
The Radium Engineering Master Cylinder Brace stiffens the brake master cylinder against the driver-side shock tower on the Subaru BRZ, Scion FR-S, and Toyota 86 / GR86 (LHD models). Eliminating firewall flex under heavy braking, it delivers a firmer, more communicative brake pedal with instantaneous threshold feel.
Features
- Eliminates sheet metal firewall deflection under hard braking to dramatically firm up pedal feel
- Provides immediate brake modulation and crisp pedal feedback during threshold deceleration
- CNC machined from 6061-T6 billet aluminum and black anodized for corrosion resistance
- Adjustable pre-load bolt with protective nylon foot prevents damage to the master cylinder casting
- Direct bolt-on installation utilizing existing factory shock tower mounting holes on LHD vehicles
