PERRIN 08-14 Subaru WRX/STI / 08-11 Impreza / 09-13 Forester XT Differential Subframe Lockdown Syst

PERRIN 08-14 Subaru WRX/STI / 08-11 Impreza / 09-13 Forester XT Differential Subframe Lockdown Syst

Improve rear differential stability with the Perrin Performance PSP-SUS-535 Differential Subframe Lockdown System. Designed for select Subaru WRX, STI, Impreza, and Forester XT models, this system helps reduce unwanted movement in the differential subframe during acceleration, shifting, and cornering. By reinforcing the connection between the differential subframe and chassis, it supports more consistent drivetrain behavior and improved power delivery.

The Perrin Performance lockdown system is engineered for enthusiasts seeking sharper response without replacing the complete rear subframe assembly. Its application-specific design provides a secure fit for compatible Subaru platforms, including 2008-2014 WRX and STI models, 2008-2011 Impreza models, and 2009-2013 Forester XT models. Verify vehicle compatibility before installation to ensure proper fitment.

Built for performance-oriented street cars, autocross vehicles, and track applications, the PSP-SUS-535 helps address differential subframe deflection that can contribute to drivetrain slack and inconsistent handling. The system is supplied as one vehicle-specific solution from Perrin Performance and is intended for installation with standard automotive tools and appropriate safety procedures. Professional installation is recommended for customers who prefer expert fitment and torque verification.
