Using these ABW fender flares is simple. First, you'll get them about two weeks after placing your order. When you receive them, start by prepping the area on your Subaru WRX or STI where the flares will be installed. This might involve cleaning and making sure the surface is smooth. Then, bolt or screw the flares into place. For the front ones, it's a single - piece installation, and for the rear, fit the two - piece flares around the door opening. As for maintenance, keep them clean by washing with a mild soap and water. If you notice any chips in the white gelcoat, you can touch them up with paint. Also, since you need to paint them to match your car, make sure to use a paint that's suitable for fiberglass. Remember, these are made - to - order products, so give them the care they deserve to keep your car looking great.
