The Perrin Performance Differential Subframe Lockdown System is engineered to increase chassis rigidity and reduce unwanted differential movement in a wide range of Subaru models. Designed for the 2008–2014 WRX/STI, 2008–2011 Impreza, and 2009–2013 Forester XT, this system reinforces the subframe mounting points to help deliver sharper handling response, better cornering stability, and improved drivetrain feedback during spirited driving.
Constructed from high-quality, durable materials, the system integrates cleanly with the vehicle’s factory hardware for a tight, secure fit. By minimizing subframe flex, the Lockdown System enhances overall stability whether you’re navigating backroads, carving through corners, or exploring off-pavement terrain. Installation is straightforward for those experienced with suspension or drivetrain components, and the upgrade provides an immediate, noticeable improvement in the vehicle’s composure.
Built by Perrin Performance—well known for precision engineering and strict quality control—this lockdown system provides long-lasting reliability and is a valuable addition for Subaru owners seeking improved performance on the street or track.
