Bilstein B16 2004 Audi S4 Base Front and Rear Performance Suspension System

What you get here is a complete front and rear performance suspension system from Bilstein, specifically the B16 PSS9 kit. This isn't just a set of shocks and springs; it's a carefully matched package designed to give your 2004-2009 Audi S4 a significant handling upgrade. Bilstein is known for its German engineering, and this kit brings that expertise to your car, featuring monotube dampers and matched springs that are tuned for the S4's specific weight and dynamics.

The real magic of the B16 system is its adjustability. You get 9 stages of damping adjustment, which controls both rebound and compression with each click. This means you can dial in the suspension to suit your driving style or the road conditions, whether you're on a track day at the Nürburgring or just want a more controlled feel on your daily commute. The threaded body allows you to lower the car between 30mm and 50mm, letting you achieve that perfect stance and center of gravity. Plus, the zinc-coated, threaded bodies and Triple-C coating offer solid protection against corrosion, keeping your investment looking and performing well for a long time.

Installing this kit will change how your S4 handles, providing a more connected feel to the road. You'll notice improved stability in corners and a more responsive steering feel. While this kit is designed as a direct fit, it's always a good idea to consult the manufacturer's installation instructions for the best results, especially when setting your ride height and damping levels.
