Master Cylinder Brace for 2015+ Subaru WRX / STi

The PERRIN Performance Master Cylinder Brace significantly reduces flex at the firewall, so you get a solid brake pedal feel with every application of the brakes. This is very noticeable while under heavy braking and even slowing for a stop sign. The difference can be felt immediately after installation.

Your brake pedal is connected to the thin sheet metal firewall which flexes as you apply the brakes. The firewall is not stiff enough to deal with the constant and repeated forces while applying the brakes. The PERRIN Master Cylinder Brace creates a bridge between the firewall, master cylinder, and shock tower, significantly reducing flex in the firewall while braking.

When possible PERRIN Performance tries to design Master Cylinder Braces in one piece to improve rigidity. The PERRIN Performance Master Cylinder Brace for the 2015 WRX/STI is CNC machined from a large piece of 6061-T6 billet aluminum for extreme stiffness. With stainless steel hardware and an anodized finish, the Master Cylinder Brace will look great and last the life of the car, even in the harshest conditions.

The PERRIN Performance Master Cylinder Brace is designed to attach strategically to multiple points on the shock tower. This helps reduce flex in the brake master cylinder by creating a stable connection between it and the chassis. To further aid in stiffening or tightening up this connection, included is an adjustable screw that allows tension to be preloaded on the master cylinder.
