Product Description

The PERRIN PSP-SUS-042RD Rear Shock Tower Brace is engineered for the 2022-24 Subaru WRX to increase rear chassis rigidity and reinforce the connection between the twin rear shock towers. In demanding driving conditions - autocross, track days, or spirited street driving - chassis flex in the rear can affect suspension geometry and handling precision. By tying the towers together, this brace helps minimise that unwanted movement and deliver sharper handling and improved driver feel.

Installation is straightforward: remove any factory rear brace (if equipped), align the CNC-machined mounting feet over the designated towers, bolt in the new bar, and torque to specification. With its high-strength aluminium bar and bold red finish, it provides both performance and visual enhancement to the rear suspension system of the WRX. If you are looking to upgrade the rear end of your 2022-24 WRX for better handling and responsiveness, this PERRIN brace is a high-quality solution.
