Subaru STi Diff Subframe Lockdown - Rear - Perrin Performance - `04-`07. A focused rear differential lockdown designed to reduce differential movement and deliver crisper drivetrain feedback for your 2004–2007 STi.

The Perrin rear differential lockdown is engineered to increase drivetrain rigidity and help translate engine torque more predictably to the wheels. By limiting unwanted movement of the rear differential relative to the subframe, drivers often notice improved throttle response and a firmer feel during cornering and hard acceleration. This part is built to integrate with the vehicle’s existing rear subframe and differential mounting arrangement for a factory-compatible solution.

• Designed for 2004–2007 Subaru STi rear differential/subframe configuration
