Using these fender flares is a great way to enhance your Subaru WRX or STI's look. First, make sure your car is clean before installation. You'll need to prep the flares for a final fit and then paint them to match your car's color. Since they are made to order, expect them to ship 2 weeks after you place your order. For maintenance, simply wash them with mild soap and water regularly. Avoid using harsh chemicals as they might damage the white gelcoat finish. Keep them away from sharp objects to prevent scratches. If you notice any chips or damages, you can touch - up the paint as needed.
