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. Material: ASA (Acrylnitril-Styrol-Acrylester) ASA is a highly technical polymer for outdoor use. This synthetic material is characterised by its particularly high strength, stiffness and weather resistance. ASA owes these properties to its special ingredient: acrylic ester rubber. We process ASA as sheet material, i.e. the parts are milled "from the solid material". The high-quality, matt, shiny and scratch-resistant black surface, which is typical for ASA, is also worked out. The ASA surface does not require any further treatment; AC Schnitzer aerodynamic components made of ASA can be installed directly. Of course, painting is still possible on request. After the surface of the ASA material has been pre-treated, it can be painted in any colour. Creative Design PUR, ASA or 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. For example, crash tests using dummies confirm that pedestrian protection requirements are fulfilled. Only when all tests have been passed and the homologation certificate has been issued are AC Schnitzer aerodynamic components released for sale worldwide. Expert Opinion The approval of AC Schnitzer special parts for road traffic is a central goal for us when developing new components. This is also decisive for the development of new aerodynamic components. However, some parts are not subject to approval. We have had an expert opinion prepared for such parts. This serves to prove that the corresponding part complies with the regulations and states that no risk is to be expected when the part is installed as intended, which is why the part can be used without restriction. Acceptance of the installation or mounting is not required. According to § 19, para. 2 StVZO the operating permit of the vehicle does not expire.
