BMW i4 G26 Boot/Trunk Spoiler, Carbon Fibre (AC SCHNITZER)

Product Information:

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: Carbon Fibre Reinforced Plastic
Carbon-fibre-reinforced plastic - or carbon for short - has a unique quality. Carbon is ultralight, but at the same time extremely rigid. These properties explain why this material has become essential in motorsport and aerospace technology.

However the fibres are expensive and complex to produce. Fibres are spun into thick threads known as rovings, which are woven into textile-like fibre mats.

These are then impregnated with different plastics in a further step, at which point the material becomes very fragile. Even slight stretching will lead to irreparable distortion in the texture and make the product unusable. Working only by hand, skilled craftsmen can make this ultra-delicate fabric into complex shapes. Such a work process requires extensive experience and fingertip feel.

When the components have been hardened in the autoclave, the surface is lacquered. This is a very sophisticated process because of the many indentations in this fabric-like structure. So the flawless surface finally reflects one factor above all: perfection down to the lowest fibre.

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.

Homologation Certificate
The parts homologation certificate is an official document which allows the use of tuning parts in public road traffic within the framework of the (StVZO) German road traffic licensing regulations (and some other countries). After installation or conversion of the part described in the certificate, the vehicle must be presented to an official inspection body. The inspector determines the correct installation and the authenticity of the part and subsequently enters the modification in the vehicle documents. The official operating license of the vehicle thus remains in force. The parts homologation certificate is part of the scope of delivery.
