The Alpha-N Carbon Rear Diffuser V2 for the BMW G90 / G99 M5 represents the next evolution of Alpha-N’s aerodynamic development for BMW’s latest M5 platform. Designed and manufactured in Germany, the V2 diffuser introduces a significantly more aggressive and functional layout compared to the original V1 design while maintaining precise OEM-level fitment.
Constructed from premium pre-preg carbon fiber using a 2x2 twill weave, this diffuser is engineered with both aesthetics and performance in mind. The updated V2 design incorporates integrated underbody-style sections around the center of the diffuser which help improve airflow management beneath the vehicle. These additional aerodynamic surfaces contribute to increased rear-end stability by helping generate additional downforce while also reducing aerodynamic drag at higher speeds.
Alpha-N produces their carbon components using advanced manufacturing techniques and high-quality pre-preg carbon fiber sourced from Italy. Each diffuser is developed with a motorsport-inspired design philosophy, bringing functional aerodynamic solutions from racing environments to road-going vehicles. The result is a component that enhances both the visual presence and aerodynamic efficiency of the G90 M5 sedan and G99 M5 Touring.
This V2 diffuser arrives with a factory gloss clear coat finish and is ready for installation. The component mounts using the factory mounting tabs integrated into the OEM rear bumper cover to ensure proper alignment and secure fitment. A matching Alpha-N carbon tow hook cover is included, which must be bonded to the factory tow hook cover during installation.
