Using your Bilstein B16 (PSS10) suspension kit is easy. First, adjust the damping settings according to your driving needs. For a smooth, comfortable daily drive, turn the dial to a lower number. If you're going to the track or want a more aggressive driving experience, choose a higher setting. To adjust the ride height, use the threaded body on both axles. You can make these adjustments to achieve the right balance for your vehicle. When installing, be aware that some wheel/tire combinations may require wheel spacers. Make sure to check this before you start the installation. As for maintenance, since the suspension has a surface coating using Triple - C - Technology®, it has good corrosion resistance. But it's still a good idea to regularly check for any signs of damage or wear, especially after driving on rough roads or in extreme conditions. Keep the springs and shock absorbers clean, and if you notice any issues, consult a professional mechanic.
