AC Schnitzer suspension spring kit for BMW M4 G83 Convertible

Philosophy / Technology / Voting

AC Schnitzer's suspension components improve driving dynamics and safety. This requires the wheels to maintain contact with the road at all times, ensuring good roadholding, cornering stability, and braking and steering reliability. "The car's handling must essentially match that of the production car. Smooth load-change responses and gentle understeer at the limit are important—after all, AC Schnitzer customers aren't professional racing drivers," explains Roman Fenners, Head of Development at AC Schnitzer.

With us, every chassis goes through the "Green Hell".

Only when a suspension has achieved optimal results under all conceivable driving and racing conditions and combines sporty handling with the highest possible suspension comfort can it be offered as an original AC Schnitzer suspension spring set, sports suspension or RS coilover suspension. The AC Schnitzer test team is responsible for the exceptionally high product quality of all suspension components. AC Schnitzer suspension components are produced in close cooperation with renowned suspension manufacturers. The special and exclusive AC Schnitzer setup is immediately apparent to the customer. Because only where AC Schnitzer is written on it, you will actually find an AC Schnitzer setup, and this is unique for each model. Since the production models sometimes differ significantly from one another, the engineers have to develop separate suspension components for each model. Vehicle weight, size, engine size and wheel/tire combinations are all taken into account individually. Ultimately, everything must be optimally tailored to the respective vehicle and its characteristics.

Appraise

The parts certificate is an official document that permits the use of tuning parts on public roads under the StVZO (Road Traffic Licensing Regulations) in Germany (and several other countries). After the part described in the certificate has been installed or modified, the vehicle must be presented to an official inspection center. The inspector will verify the correct installation and authenticity of the part and then enter the modification in the vehicle documents. The vehicle's official operating license thus remains valid. The parts certificate is part of the delivery package.
