Perrin Master Cylinder Brace 2015-2021 WRX/STI

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. The brace attaches strategically to multiple points on the shock tower. This helps reduce flex in the brake master cylinder by creating a solid 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.
