Some exterior accessories are meant for styling while others for functionality. There is another class of add-on pieces that not only upgrade your car's looks but are also very useful in making it more versatile. The Audi 4000S fender flares are the best example of such exterior upgrades that decorate the car while keeping way the road debris that can blemish the paint. With the new Audi 4000S carbon fiber fender flares you can make the wheels look wide and bold. You get the same effect that is otherwise attainable with an Audi widebody kit. It's the easiest way of getting a remarkable change in the outward show of your vehicle.
