Akrapovic WI-BM/CA/1/CF Rear Wing for BMW G-Series Performance
Akrapovic WI-BM/CA/1/CF Rear Wing: Premium Aerodynamics for BMW G-Series Performance Models
The Akrapovic WI-BM/CA/1/CF Rear Wing (Forged Carbon) is one of the most visually striking and performance-driven aerodynamic upgrades available for modern BMW G-series performance cars. Designed specifically for the BMW M2, M240i, M3, M340i, M4, and M440i (G87, G42, G80, G20, G82, G22), this rear wing blends cutting-edge motorsport-inspired engineering with premium materials to deliver improved stability, enhanced downforce, and a bold aesthetic upgrade. For drivers who demand the perfect balance of style and performance, this forged carbon rear wing is a standout choice.
What the Akrapovic Rear Wing Does
This rear wing is engineered to improve aerodynamic efficiency by generating downforce at high speeds. Downforce helps press the vehicle's rear tires onto the road, improving traction, cornering stability, and high‑speed confidence. Whether installed on a daily‑driven BMW M340i or a track‑focused BMW M2, the Akrapovic WI-BM/CA/1/CF Rear Wing helps optimize airflow and reduce drag while contributing to a planted, performance‑oriented driving feel.
Unlike purely cosmetic spoilers, this Akrapovic rear wing incorporates aerodynamic principles derived from motorsport, including a precisely shaped aerofoil and a small trailing-edge lip for additional stability. Every detail of its construction is engineered for functionality as well as aesthetics.
Premium Materials and Motorsport-Inspired Construction
One of the standout features of the Akrapovic WI-BM/CA/1/CF Rear Wing is its forged carbon fiber construction. The use of hand-crafted chopped carbon fibre creates a unique visual pattern, and the part is finished with a high‑gloss lacquer for a striking, premium appearance. Forged carbon not only looks distinctive but also offers superior strength-to-weight characteristics compared to traditional carbon fiber.
The wing is mounted using CNC‑machined aluminum brackets with a swan‑neck design—a layout frequently seen in high-level motorsport. This design positions the mounting points above the wing surface, keeping airflow underneath the wing cleaner and allowing the aerofoil to work more efficiently. Titanium bolts and reinforcements at the pivot points further improve durability and reduce overall weight.
Aerodynamic Optimization for BMW G-Series Models
To ensure perfect compatibility and optimal performance, Akrapovic used advanced computational fluid dynamics (CFD) to tailor the wing for several BMW G-series models. The wing is specifically optimized for the BMW M2 and M240i but is fully compatible with M3, M4, and corresponding 40i variants as well.
CFD testing ensures that installing the Akrapovic WI-BM/CA/1/CF Rear Wing does not introduce unnecessary air turbulence or unwanted wind noise. Instead, the wing works with the car’s natural aerodynamic profile to enhance stability without compromising comfort or efficiency.
Fully Adjustable for Personalized Performance
The rear wing features a three‑stage manual adjustment system, allowing owners to tailor the angle of attack to match their driving needs. A steeper setting increases downforce for track use, while a flatter angle reduces drag for everyday or highway driving. This flexibility makes the wing valuable for both road and performance applications.
Additionally, the wing carries ABE approval (AKR-WI KBA 31882), meaning it meets strict European safety and quality standards. The understated monochrome Akrapovic logo on each side adds a refined finishing touch without overwhelming the clean, motorsport-style design.
Why Buy the Akrapovic WI-BM/CA/1/CF Rear Wing?
