Bilstein B16 2003 BMW Z4 2.5i Front and Rear Performance Suspension System

This is the Bilstein B16 (PSS9) performance suspension system, designed specifically for your 2003-2008 BMW Z4 2.5i. If you're looking to get a more connected feel to the road and the ability to fine-tune your car's handling, this kit is a solid choice. It replaces your factory struts and springs with a matched set of monotube dampers and performance springs, all built to Bilstein's standards.

What sets this kit apart is the adjustability. You get 9 stages of damping adjustment that control both rebound and compression with each click, letting you dial in the ride for different conditions, whether you're on a track day or just want a firmer feel for spirited driving. The threaded body design also allows you to lower your Z4 anywhere from about 30mm to 50mm, giving you that aggressive stance and a lower center of gravity. The zinc-coated, threaded bodies are built to resist corrosion, even in harsh weather.

This kit is made in Germany and has been tested under demanding conditions, including at the Nürburgring. It's a complete package designed for a direct fit, meaning it bolts onto your Z4 without needing major modifications. You'll get a well-built suspension system that offers a significant improvement in handling and a customizable ride height.
