Bilstein B16 (PSS10) Subaru WRX STi Base/Limited H4 2.5L Front & Rear Performance Suspension System

If you're looking to dial in the handling of your 2015-2021 Subaru WRX or WRX STI, this Bilstein B16 (PSS10) suspension system is a serious upgrade. This kit replaces your factory struts and springs with a matched set of performance dampers and springs, giving you the ability to fine-tune both ride height and damping characteristics. It's designed to give you more control and a sportier feel, whether you're driving on the street or pushing it on the track.

What sets this kit apart is the 10-stage damping adjustment. Each click changes both rebound and compression simultaneously, making it straightforward to find the sweet spot for your driving style and conditions. You can lower your car by about 30mm to 50mm using the threaded bodies, which also feature a zinc coating for excellent protection against corrosion and road salt. Bilstein tests these systems extensively, even on demanding tracks like the Nürburgring, so you know they're built for performance.

This is a complete front and rear kit, meaning it includes everything needed to transform your car's suspension. The monotube dampers are tuned specifically for the WRX and WRX STI, ensuring they work well with the included springs. Installation is designed to be a direct fit, replacing your stock components without needing major modifications.
