WI-BM/CA/1/G
Rear Wing (Carbon) for






Manufactured from lightweight hand-crafted carbon fibre, this product is lacquered to create a high-gloss finish. It is mounted on two brackets with a swan neck design, fabricated from lightweight CNC-machined aluminium to provide the best ratio between weight and performance. The brackets have been optimized to provide the optimum ratio between load-bearing capacity and weight. The bolts used to connect the wing and the brackets are high-grade titanium. High-grade titanium reinforcements have been incorporated for better structural stability at pivot points. Designed with echoes from the motorsport world, the derived aerofoil of the wing was developed to achieve an extremely competitive ratio between downforce and drag. A small lip is placed at the trailing edge of a wing to achieve maximum performance of the wing by creating even more downforce.
Optimized for the aerodynamics of the BMW M3 and M4, computational fluid dynamics (CFD) has been used to ensure the best functionality, and great attention has been paid to guaranteeing that the overall geometry does not cause additional air turbulence around the rear or generate additional noise on the side of the car.
Fully adjustable to three levels, the wing needs to be manually set to the preferred angle before driving. It is ABE approved with AKR-WI KBA 31882 type approval and finished with an understated Akrapovič monochrome logo on each side.
The product also fits on M4 LCI version.
This product does not fit on BMW M4 Cabrio (G83).
This product does not fit on the BMW M440i Cabrio (G23) model.
