Bilstein B12 Pro-Kit 2015-2017 Subaru WRX STI Front and Rear Monotube Suspension Kit

If you're looking to improve the handling and stance of your 2015-2021 Subaru WRX STI, this Bilstein B12 Pro-Kit is a complete solution. It pairs Bilstein's well-known B8 Performance Plus monotube dampers with Eibach Pro-Kit springs, specifically tuned for your STI. This combination is designed to give you a noticeable improvement in driving dynamics, offering better control and a more connected feel to the road.

The B12 Pro-Kit is engineered to provide a fixed, moderate lowering of your vehicle, typically between 25-40mm depending on your specific STI model. This drop not only enhances the car's aggressive look but also lowers the center of gravity, which contributes to reduced body roll during cornering. The monotube design of the Bilstein dampers allows for consistent damping performance, even under demanding driving conditions, while the progressive rate Eibach springs offer a balance between comfort and sporty responsiveness. You can expect a more precise steering response and a solid feel when pushing your STI through its paces.

This kit includes everything needed to upgrade both the front and rear suspension. The springs are designed with progressive characteristics, meaning they adapt to different driving inputs – softer for everyday cruising and stiffer when you need more support during spirited driving or hard braking. It's a well-rounded package that aims to raise your car's performance envelope while maintaining a comfortable ride for daily use.
