Perrin Master Cylinder Brace 2015-2021 WRX/STI

The PERRIN Master Cylinder Brace prevents unwanted movement of the master cylinder, allowing for increased brake pedal stiffness and response.

REDUCE FLEX

Your brake pedal is connected to the thin sheet metal firewall which flexes as your 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.

STIFFEN BRAKE PEDAL FEEL

The PERRIN Master Cylinder Brace significantly reduces flex at the firewall, so you get 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 immediately be felt after installation.

CONSTRUCTION

DESIGN

The PERRIN Master Cylinder Brace is designed to attach to strategically to multiple points on the shock tower.
