Perrin 08-12 STi Hatchback / 11-12 STi Sedan Master Cylinder Bracket

The PERRIN Master Cylinder Brace locks down the master cylinder preventing unwanted movement due to a weak firewall. Allowing the driver to regain maximum braking force and increased pedal stiffness. The thin sheet metal firewall isn't able to deal with the constant forces from repeatedly applying the brakes in all conditions. Over time it begins to flex and give as the brake pedal is depressed. The PERRIN Master Cylinder Brace creates a bridge between the firewall, master cylinder and shock tower, eliminating flex in the firewall while braking. The PERRIN Master Cylinder Brace eliminates the flex at the firewall, so you feel nothing but solid pedal feedback with every application of the brakes. Even slowing for a stop sign, the difference can immediately be felt after installation of the PERRIN Master Cylinder Brace. The PERRIN Master Cylinder Brace is constructed of CNC Machined 6061 aluminum, and CNC formed Steel. This combination of different materials are used to add extra support
