Bilstein B6 2015-2017 Subaru WRX - STI Rear Monotube Strut Assembly

The Bilstein B6 monotube design uses gas pressure to keep the fluid and gas separated, which helps prevent foaming and ensures consistent damping performance. This is a direct replacement for your rear strut assembly on your 2015-2021 Subaru WRX and WRX STI, designed to work with your factory springs. It's a well-built upgrade that brings out the best handling your car can offer, improving grip and stability whether you're navigating daily commutes or more demanding driving situations.

Bilstein tunes each B6 damper specifically for the vehicle it's going on, meaning this strut assembly is valved to match the characteristics of your WRX or STI. This vehicle-specific tuning helps deliver improved safety and better lane stability without needing to change your existing springs. You'll notice a difference in how the car feels, especially during cornering and quick maneuvers, all while maintaining a comfortable ride.
