Using this APR Carbon Fiber License Plate Frame is easy. First, gather the included hardware and tool. Then, place the frame around the rear license plate of your 2008 - 2014 Subaru WRX or 2011 - 2014 STI sedan. Secure it with the provided hardware. When it comes to maintenance, regularly clean the frame with a mild car cleaner. Avoid using abrasive materials as they might scratch the carbon fiber. Keep the car parked in the shade as much as possible to reduce the effects of UV light on the fade - resistant epoxy coating. And always remember, this frame is designed for sedan models only, so don't try to fit it on other types of vehicles.
