Using these Noble STI style carbon fiber rear spats is a breeze. First, gather all the included hardware. Make sure your Subaru WRX (2022 - 2025) is clean where you'll be installing the spats. Follow the simple instructions that come with the kit to attach the spats to your car. It's important to handle the spats carefully as they are made of fiberglass with a carbon fiber finish. Avoid hitting or scratching them during installation. For maintenance, just wash them regularly with mild soap and water. Don't use any abrasive cleaners as they could damage the carbon fiber finish. If you notice any loose parts after installation, check the hardware and tighten it up. With proper use and care, these rear spats will keep your car looking great for a long time.
