Using this license plate panel is super easy. First, gather all the included hardware like the 3M and longer screws. In just a few minutes, you can install it on your 2015 - 2021 WRX or STI. Make sure to mount your license plate with the provided hardware. After installation, take a light rubbing compound and a microfiber cloth. Gently rub the panel to make it shine.
