Using this coilover kit is quite straightforward. Just follow the installation instructions that come with it. For everyday driving, you can leave the dampers at a setting that suits your comfort. If you're going to the track, you can adjust the dampers to a stiffer setting for better control. When it comes to maintenance, check the dampers regularly for any signs of leakage or damage. Keep the coilover clean to prevent dirt from affecting its performance. Remember, the build time is usually 4 weeks, so plan your installation accordingly. And the 5 - year manufacturer's warranty gives you peace of mind, but always follow the usage guidelines to avoid voiding it.
