Using the GrimmSpeed Bumper Bar on your 2015 - 2021 Subaru WRX or STI is straightforward. First, make sure to check if your vehicle is the correct model and year. Then, carefully install the bumper bar according to the provided instructions. Remember, this bar is not a substitute for the OEM crash protection, so drive safely as usual. When it comes to maintenance, keep it clean by washing it regularly with mild soap and water. Avoid using harsh chemicals that could damage the wrinkle black powder - coat finish. Also, since it's designed for the GrimmSpeed Front Mount Intercooler Core, if you plan to change your intercooler, check the compatibility. The integrated tow hook is for the license plate relocation kit, not for pulling or recovering your vehicle, so don't use it for that purpose.
