Race-Inspired Aerodynamics for the BMW G80 M3, G82 M4 and G87 M2
The Akrapovic WI-BM/CA/1/G Rear Carbon Wing transforms the aerodynamic profile of the 2021 and newer BMW G87 M2, G80 M3 and G82 M4 with a hand-laid pre-preg carbon fiber structure that is autoclave cured for maximum strength and minimum weight. Engineered to mirror the aggressive stance of the factory BMW M4 CSL, the WI-BM/CA/1/G delivers measurable rear downforce to raise stability at track speeds while shaving 1.8 kg compared to a steel equivalent. A UV-protected high-gloss clear coat preserves the carbon weave for seasons of track and street use. A separate Akrapovic fitting kit (WI-BM/CA/1/FK) is required and sold separately.
Key Features
- Hand-Laid Pre-Preg Carbon Fiber — Autoclave curing eliminates voids and delivers consistent wall thickness for structural rigidity and class-leading strength-to-weight ratio.
- High-Gloss UV-Protected Finish — Multi-stage clear coat resists fading, yellowing and stone chips through extended track and street exposure.
- CSL-Inspired Aerodynamic Profile — Designed to generate rear downforce on all G80/G82/G87 variants for measurable gains in high-speed stability and cornering confidence.
- Precise Chassis-Specific Engineering — Mounting points align directly with factory G80, G82 and G87 body locations using the matching Akrapovic fitting kit.
- Race-Pedigree Brand — Developed using Akrapovic composite expertise honed in MotoGP, WorldSBK and FIA GT competition programs.
- Fitting Kit Required — WI-BM/CA/1/FK sold separately ensures clean OEM-quality installation with hidden hardware and factory-quality alignment.
