Using the Bilstein B16 suspension kit is easy. First, make sure your vehicle is on a flat and stable surface. Adjust the 9 - stage dampers according to your driving style and road conditions. If you're on a smooth track, you might want a stiffer setting for better handling. For rough roads, a softer setting will give you a more comfortable ride. When adjusting the ride height, turn the threaded body carefully until you reach your desired height. As for maintenance, regularly check the zinc - coated parts for any signs of damage or corrosion. If you notice any issues, clean the parts and apply a protective coating. Also, make sure to keep the dampers lubricated as recommended in the product manual. Always follow the safety instructions when working on your vehicle to avoid any accidents.
