Subaru STI Rear Subframe Lockdown - Perrin Performance - 2015–2025. This PERRIN Rear Subframe Lockdown kit reduces drivetrain movement during hard acceleration, braking, and cornering to give a more responsive, connected driving feel for street and track use.

The kit is engineered to limit rear subframe motion that can cause inconsistent throttle response and unsettled handling. By securing the subframe more firmly to the chassis, the PERRIN Lockdown helps deliver a more predictable rear end under load, improving driver confidence during aggressive maneuvers without altering suspension geometry. Designed for 2015–2025 Subaru WRX/STI applications, it’s a focused upgrade for enthusiasts looking to tighten chassis feedback.
