Using your Seibon NSM - style carbon fiber rear spoiler for your 2009 - 2020 Nissan 370Z is straightforward. Just follow the installation instructions that come with it. When it arrives, make sure to check for any damage right away. If you notice anything wrong, tell us immediately. For maintenance, clean it regularly with a soft cloth and a mild cleaner. Avoid using harsh chemicals that could damage the carbon fiber. Store it in a cool, dry place when not in use to keep it in good condition.
