Using this Noble Carbon Fiber JDM Style Front Lip is easy. First, gather all the supplied hardware. Then, find a flat and stable surface to work on. Place your car on it and make sure it's in a safe position. Line up the front lip with the front of your 2015 - 2021 Subaru WRX or STi. Use the hardware to bolt it on tightly. Make sure all the bolts are secure. As for maintenance, keep it clean by washing it regularly with a mild car wash soap and a soft cloth. Avoid using abrasive cleaners that could scratch the carbon fiber finish. Also, when parking your car, be careful not to hit the front lip on curbs or other objects. If you notice any loose bolts over time, simply tighten them up. This will help keep your front lip looking great and performing well for a long time.
