The Alpha-N G90 / G99 M5 Carbon Rear Diffuser – V1 enhances the rear styling of the latest BMW M5 while maintaining the refined design language of the G9X platform. Designed and manufactured in Germany using premium pre-preg carbon fiber sourced from Italy, this diffuser delivers a subtle yet purposeful motorsport appearance while improving aerodynamic efficiency.

Unlike overly aggressive aftermarket diffusers, the Alpha-N V1 diffuser expands slightly on the factory rear diffuser design to accentuate the existing bumper lines and rear proportions of the G90 M5 sedan and G99 M5 Touring. The result is a cleaner carbon fiber upgrade that complements the vehicle’s design while adding a lightweight motorsport aesthetic.

Constructed using Alpha-N’s high-quality pre-preg carbon fiber process, the diffuser features a classic 2x2 twill weave finished in a durable gloss clear coat that highlights the carbon fiber pattern while protecting the surface from UV exposure and environmental wear. The diffuser installs using factory bumper clips and OEM mounting points, ensuring proper fitment and structural integrity.
