Using your Fortune Auto 500 Series Gen 8 Coilover Kit is straightforward. First, make sure to adjust the height and damping according to your driving needs. For everyday driving, a medium setting on the 24 - step adjustable dampers usually works well. If you're planning to hit the track, you can increase the stiffness for better handling. When it comes to maintenance, regularly check for any signs of leakage or damage. Keep the coilovers clean and lubricate the moving parts as recommended. Remember, this kit has a 5 - year manufacturer's warranty, but proper care will ensure its longevity. If you have any questions or need further assistance, don't hesitate to contact our support team.
