Using these side skirts is simple. Just have them installed by a professional mechanic on your 2009 - 2020 Nissan 370z. When the product arrives, make sure to thoroughly check it for any damages during transit. If you spot any issues, let us know immediately. As for maintenance, clean the carbon fiber side skirts regularly with a mild soap and water solution. Avoid using harsh chemicals that could damage the carbon fiber. Keep them in a dry place when your car is not in use to prevent long - term damage. And remember, since these are custom - built items, pre - ordering means you'll need to wait 8 - 12 weeks, but the result is definitely worth it.
