Perrin Rear Subframe Lockdown Kit 2015-2025 WRX / 2015-2021 STI / 2022-2025 BRZ | CNC Aluminum | Rear Subframe Reinforcement Kit
Overview
The Perrin Rear Subframe Lockdown Kit is engineered to enhance the rear chassis rigidity of your Subaru WRX, WRX STI, or BRZ by significantly reducing drivetrain movement and subframe flex. This kit is ideal for enthusiasts seeking a more connected and responsive driving experience, particularly during aggressive acceleration, cornering, and shifting. By locking down the rear subframe and differential, it minimizes unwanted slop that can detract from power transfer and handling precision.
Crafted from CNC-machined aluminum paired with high-durometer urethane bushings, the Perrin kit reflects a design philosophy focused on durability and performance without compromising daily drivability. The anodized aluminum spacers provide a lightweight yet robust solution, while the premium bushings maintain a balance between stiffness and NVH control. This approach ensures that the lockdown kit delivers tangible improvements in chassis response without introducing excessive noise or vibration.
For Subaru owners, especially those who push their vehicles on the street or track, this lockdown kit translates to improved traction and more predictable rear-end behavior. Reducing wheel hop and rear subframe movement helps maintain stability under load, enhancing launch performance and cornering confidence. The direct bolt-on design means you can upgrade your Subaru’s rear end with minimal hassle, preserving factory fitment and serviceability.
