Using this front lip is super easy. First, gather all the hardware that comes with the product. Then, position the front lip on your 2015 - 2021 Subaru WRX or STi according to the provided instructions. Use the bolts and other hardware to secure it in place. Make sure it's firmly attached so it stays in position while you're driving. When it comes to maintenance, regularly clean the carbon fiber finish with a soft, damp cloth. Avoid using abrasive cleaners as they can scratch the surface. Also, check the bolts periodically to ensure they're still tight. If you notice any loose bolts, tighten them right away. When parking, try to avoid hitting the front lip on curbs or other obstacles to prevent damage.
