Using this skid plate kit is easy. First, make sure your kart has 30mm tubing as this kit is designed for it. Place the front skid plate in the right position at the front of your kart. Then, attach the side skid plates on the sides. Since mounting hardware is not included, you'll need to get suitable ones. When using your kart, the skid plates will protect it from scratches and minor impacts. As for maintenance, after each use, simply wipe the skid plates with a clean cloth to remove dirt and debris. If there are any signs of rust, you can use a mild metal cleaner to clean them. Store the kart in a dry place to prevent rusting of the skid plates.
