Perrin Brake Master Cylinder Brace for 22+ GR86 Models.

The Perrin Master Cylinder Brace creates a bridge between the firewall, master cylinder, and strut tower and prevents unwanted movement of the master cylinder, allowing for increased brake pedal stiffness and response. This Brace significantly reduces flex in the firewall while braking, and becomes more noticeable the harder that you are braking.
