Using these fender flares on your Subaru Forester SG is a breeze. First, you'll need to cut the original flares to ensure there's enough space for full wheel travel. Then, simply bolt or screw the new flares into place. It's important to prep the flares and do a final fit before painting them. Since these are made to order, expect them to ship two weeks after you place your order. As for maintenance, keep them clean with a mild soap and water. Avoid using harsh chemicals that could damage the white gelcoat finish. And remember, these flares won't fit the Forester SF model, so make sure your vehicle is the right fit.
