Using the Bilstein B16 suspension kit is quite straightforward. First, make sure your vehicle is on a flat and stable surface. When adjusting the 9 - stage dampers, turn the adjustment knob slowly to find the right setting for your driving style. For a smooth ride, start with a middle setting and adjust as needed. When it comes to setting the ride height, use the threaded body design. Just turn the body to raise or lower the vehicle. Remember to check the alignment after any height adjustment. As for maintenance, regularly inspect the zinc - coated parts for any signs of damage or corrosion. Clean the dampers and springs with a mild soap and water solution, and dry them thoroughly. If you notice any unusual noises or handling issues, have the suspension system checked by a professional.
