Perrin Rear Subframe Lockdown Kit 02-07 WRX / 04-07 STI / 1998-2008 Forester / 1993-2007 Impreza | CNC Aluminum | Rear Subframe Reinforcement
Overview
The Perrin Rear Subframe Lockdown Kit is engineered to eliminate unwanted movement and flex in the rear subframe and differential of select Subaru models, including the 2002-2007 WRX, 2004-2007 WRX STI, 1998-2008 Forester, and 1993-2007 Impreza. This kit is designed for enthusiasts seeking a more connected and responsive driving experience by firming up the rear chassis components that often contribute to drivetrain slop and instability during aggressive driving.
Crafted from CNC-machined aluminum paired with high-durometer urethane bushings, the Perrin kit exemplifies precision engineering and durability. The anodized aluminum spacers provide a rigid mounting surface while the urethane bushings absorb unwanted vibrations without compromising performance. This thoughtful combination ensures longevity and consistent performance, setting Perrin apart as a leader in Subaru chassis reinforcement solutions.
By locking down the rear subframe and differential, this kit improves power transfer to the wheels, reduces wheel hop on launches, and enhances rear-end stability through corners and shifts. Subaru owners will appreciate the tighter, more predictable handling and improved traction that translates directly to a sportier, more confident driving experience without the harshness or noise often associated with stiffer bushings.
