Subaru WRX Rear Subframe Lockdown - Perrin Performance - '15-'25 is a direct-fit reinforcement kit designed to reduce subframe and drivetrain movement on 2015–2025 WRX (and WRX STI) models. It tightens the rear subframe to the chassis to deliver a more connected driving feel during aggressive driving.

This PERRIN Rear Subframe Lockdown Kit limits drivetrain movement under hard acceleration, braking, and cornering, helping to improve throttle response and steering feedback without permanent chassis modification. The kit uses durable hardware and a straightforward installation path that works with factory mounting points, making it a practical upgrade for enthusiasts who want a firmer, more predictable rear end while maintaining daily drivability.
