The 2015+ Subaru WRX PERRIN Master Cylinder Brace locks down the master cylinder preventing unwanted movement due to a weak firewall. 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.
