A unique product from our company No one has ever produced carbon fiber airflow stabilizers for BMW before. Previously BMW used similar parts on the front fenders of the rare BMW 3.0 CSL. The only production model that has such parts from the factory is the Porsche GT3 RS.
The parts are mounted on 3M double-sided tape.
“Flow stabilizers” or ‘guide fins’, play several important aerodynamic roles in sports and racing cars. Here are their main tasks:
1. Airflow Stabilization: The fins help control airflow by stabilizing the airflow on the roof and around the rear of the car. This reduces turbulence, which can cause lift and reduce traction at high speeds. By stabilizing the flow, you can provide more rear wheel traction, especially during aggressive acceleration or hard braking.
2. Improved downforce: Some fins direct air toward the rear antifender or spoiler, creating downforce that helps the vehicle grip the road. This is especially important when cornering at high speeds, when it is important to keep the car “pressed” against the track for improved handling.
3. Reduced air resistance: Properly directed airflow reduces overall aerodynamic drag. The fins can minimize the effect of turbulent swirls, which reduces drag and allows the car to move faster and more efficiently.
4. High-speed stability: Flow stabilizers help improve the vehicle's directional stability on straights and in corners, reducing the risk of deflection at high speeds due to side winds or changes in airflow direction.
Such elements have been developed in motorsport, where every detail is important to gain an advantage on the track. In sports and production sports cars, they are used to achieve better on-track performance and more stable road behavior.
