Carbon fiber wings are a great way to improve BMW 4 Series performance at speed. Since they provide downforce to the rear wheels, they add overall stability, which is important if you drive your car on the track. In addition, many BMW 4 Series carbon fiber wings are adjustable for height and angle, meaning that you can fine-tune it for maximum effectiveness. Of course, a BMW 4 Series carbon fiber wing can look just as at home on the street, and adds a high-tech look that's tough to ignore.

Carbon fiber wings are the ultimate in lightweight aerodynamics, adding downforce to help keep your BMW 4 Series rear end firmly planted to the pavement. Along with this lighter weight comes a higher price, however, as carbon fiber is an expensive material and must be laid very carefully and formed with resins. The added cost of owning a BMW 4 Series carbon fiber wing is well worth it for many, as performance and looks can be greatly improved.

Q: Why buy a carbon fiber wing?
A: Carbon fiber wings offer a great cosmetic upgrade designed customize the appearance of your car. Carbon products give your car a modern race look. Also, they have a very specific role in aerodynamics. Carbon wings defuse airflow over the top half of the car and at the trailing edge of the wing. The wing can keep airflow from tumbling and creating a swirling vortex behind the car. This is important when dealing with drag and lift.

Q: How do you install a carbon fiber wing?
A: Carbon wings are usually mounted on raised pedestals that need to be bolted into the trunk of your car. Drill holes into your trunk and bolt in the pedestals.

Q: Do carbon fiber wings fit on every vehicle?
A: Some carbon fiber wings are vehicle-specific, but most are universal. Check product descriptions to identify what fits your car. Measurements of your trunk's length and width are needed to match against the carbon wing's length and width to ensure any given universal wing will fit your car.
