Philosophy Free from the compromises of series production, AC Schnitzer develops custom components to the highest standard of perfection. “Form follows function“ - This guiding principle is systematically applied by the engineers and designers of the aerodynamic components for BMW vehicles. AC Schnitzer aerodynamic components pick up and subtly emphasise the styling lines of the base vehicle, while giving the body striking new contours. At the same time however, they have a real effect: They increase downforce on the front and/or rear axles, to ensure better ground adhesion. Only high quality composite materials, such as PU Rim or carbon, are used in production of our AC Schnitzer aerodynamic components. Because only these materials meet our high quality standard. Creative Design PUR, ASA oder Carbon: at AC Schnitzer, all draft designs originate from a true Italian artist: Michele Viandante, who has been Head Designer here for many years. Naturally his designs are not only beautiful but must prove their suitability: for example, many parts are function-tested in the wind tunnel. Testing If the calculations match the results, further tests follow. Only when all tests have been passed AC Schnitzer aerodynamic components are released for sale worldwide.
