Using your RS - R Sports - i Coilover Kit is quite straightforward. First, make sure your vehicle is parked on a flat and stable surface. Refer to the included installation guide to install the coilovers properly. You can adjust the height using the provided tools according to your preference, but it's best to follow the recommended adjustment ranges for the best ride. For damper adjustment, start with a medium setting and fine - tune it based on your driving experience. When driving, keep in mind that a lower stance might reduce ground clearance, so be careful on uneven roads. As for maintenance, regularly check the coilovers for any signs of damage or leaks. Clean them with a mild soap and water solution, and avoid using abrasive materials. If you have any issues or need further adjustment, it's advisable to consult a professional mechanic.
