Using these ABW fender flares is easy. First, make sure your 2006 - 2007 Subaru WRX or STI is clean and ready for installation. Then, position the flares on the front and rear of your vehicle as they're designed to fit around the door openings. You'll need to do some prep work, like sanding and cleaning the surface where the flares will be attached, for a better fit. After that, do a final check to ensure everything lines up correctly. Once you're satisfied, it's time to paint them to match your car's color. Remember, these flares are made to order, so they'll be shipped two weeks after you place your order. For maintenance, just wash them regularly with mild soap and water, and avoid using abrasive materials that could scratch the white gelcoat finish.
