Perrin Performance [15-26 Subaru WRX, STI and 22-25 Subaru BRZ] Rear Subframe Lockdown

The PERRIN Rear Subframe Lockdown Kit is a chassis reinforcement upgrade engineered to reduce unwanted movement in the rear subframe on 2015-2026 Subaru WRX, 2015-2021 STI, and 2022-2025 BRZ models. It’s designed to make the rear end feel more solid and responsive when you’re hustling through corners, accelerating hard, or braking deep.

• Designed to secure the rear subframe and cut down drivetrain movement under load for a more connected driving experience.
• Helps maintain chassis alignment and stability during aggressive throttle, braking, and cornering.
• Includes (2) front and (2) rear PERRIN subframe lockdown components.
• Simple bolt-on design with no permanent modifications required.
• Backed by a multi-year manufacturer warranty (60 months from purchase).
• Estimated install time ~60 minutes with basic tools.

This kit doesn’t reinvent the wheel, but it tightens what you already have — locking down the rear subframe so power isn’t lost to flex and slop when you’re asking more from the car. Perfect for enthusiasts dialed into sharpening handling without sacrificing everyday usability.
