Using this GrimmSpeed License Plate Relocation Kit is easy. First, find the OEM tow hook location on your 2015 - 2017 Subaru WRX or STI. Mount the kit there without the need for cutting or drilling. Then, use the included simple stainless steel Allen key hardware to secure it. You can adjust the license plate's position and angle as you like with the infinite - adjust design. When it comes to maintenance, since the bracket is made of powder - coated 5052 Aluminum and the tow hook adapter has a black zinc coating, it's quite durable. Just clean it regularly with a mild soap and water solution. Keep in mind that this kit only works with the OEM front bumper beam, so if you have an FMIC kit that requires bumper beam removal, it won't fit.
