Bilstein B16 2004 BMW 645Ci Base Front and Rear Performance Suspension System

This Bilstein B16 PSS9 suspension kit is a complete package designed to give your 2004-2005 BMW 645Ci or 2006-2010 BMW 650i improved handling and a customizable ride height. You get front and rear performance dampers with matched springs, all ready to install. This system is built with Bilstein's monotube technology, tested on tracks like the Nürburgring, to offer a significant step up in road feel and control.

What sets this kit apart is the ability to fine-tune your suspension. The threaded body allows you to lower your vehicle by about 30mm to 50mm, giving it a more aggressive stance. Plus, the 9-stage damping adjustment lets you dial in both rebound and compression simultaneously with each click. This means you can easily adjust the ride for different driving conditions, from spirited canyon carving to comfortable daily driving, all from one easy-to-access knob.

The dampers are built with a zinc-coated, threaded body that not only helps with ride height adjustment but also offers solid protection against corrosion from road salt and debris. Bilstein's Triple-C Coating further enhances this resistance, ensuring your suspension looks and performs well for a long time. This kit is made in Germany, reflecting a commitment to OE quality and performance engineering.
