Using these Noble side skirts is a breeze. They're designed to fit 2022 - 2025 Subaru WRX models. For installation, it's best to have two people. First, test the fit of the side skirt on your car. Once you're sure it fits well, use the self - tapping screws that come with the kit to secure it in place. As for maintenance, you can clean them with a mild car cleaner and a soft cloth. Avoid using harsh chemicals as they might damage the paint. If you notice any scratches, touch - up paint can be used according to the color of your side skirts. Keep in mind that while these ABS side skirts are durable, try to avoid hitting them against hard objects to prevent unnecessary damage.
