The exterior of your Audi S4 will get a completely new look when you install an aftermarket rear spoiler. In our on-line store, you can find the widest selection of these accessories engineered to fit your car's exact year and sub model. All products are made from the finest materials such as ABS plastic, hand-laid fiberglass, or carbon fiber, so they won't crack, rust, or break. There are several types of aftermarket spoilers that you can install on your car: factory style rear spoiler, factory style rear lip spoiler, custom style rear roofline spoiler, universal rear wing, and more.

A spoiler can produce the most dramatic results on your S4 when it reaches high speed. It will optimize airflow over the top of your car, improving its stability. Rear lip and roofline spoilers will give your exterior a more classy and appealing look. Meanwhile, an aggressively-styled rear wing will draw everyone's attention and increase downforce on your car, maximizing the contact between rear wheels with the asphalt for better grip. Nevertheless, whatever type of spoiler you choose, it will set your S4 apart from the rest and at the same time help you to express your own style and good taste.

      How Easy Is It To Install a Spoiler Myself?
      Rear spoilers are one of the flashiest yet cost-effective exterior additions you can make to your ride. The right spoiler will transform a plain-Jane family car into a sports sedan, and upgrade a sporty car into a one-of-a-kind race machine.

      Will Adding a Spoiler Make My Car More Aerodynamic?
      A simple way to answer this question would be with a "yes". However, the science of properly managing airflow to create beneficial automotive aerodynamics is, quite literally, more complicated than meets the eye. The word "aerodynamics" brings to mind visions of a vehicle in a wind tunnel with a smoke wand illustrating how smoothly air flows over it. But true automobile aerodynamics involves a detailed study of how the motion of air interacts with all areas of an automobile. One term that gets the most attention is "coefficient of drag" (Cd), which is an overall measurement of a shape's resistance to airflow.

      Why Should I Order My Spoiler Already Painted?
      When you've finally decided on the right rear spoiler or wing for your vehicle, it can't arrive quickly enough. Then, you want it to be ready for installation as soon as possible so you can begin enjoying the benefits of it. Because we understand this, we offer the option of ordering spoilers pre-painted by our manufacturers before shipping. Based on customer feedback and experiences relayed to us, we strongly recommend you consider choosing this option, for these very good reasons:

      What Kind of Spoiler is Right for You?
      The function of a rear spoiler is to control the flow of air streaming over a vehicle and properly manage it when it reaches the rear where turbulence is most likely to form. A correctly designed spoiler will counteract the lifting forces that most cars experience when speeds get high, and it will enhance rear grip by keeping a vehicle's rear end planted firmly against the road - without causing excess drag.
