The Alpha-N G90 M5 Carbon CSL Ducktail Trunk Spoiler brings classic BMW CSL styling to the latest generation BMW M5. Developed and manufactured in Germany by Alpha-N, a carbon fiber specialist known for motorsport-inspired aero design, this ducktail spoiler transforms the rear profile of the G90 M5 with a seamless motorsport appearance while improving rear-axle aerodynamic balance.

Rather than replacing the entire trunk lid, Alpha-N engineered this component as a precision-formed carbon spoiler skin designed to be bonded directly to the factory trunk lid. Once professionally installed and finished, the spoiler becomes visually integrated into the trunk panel, recreating the aggressive CSL ducktail profile while maintaining the factory trunk structure. The result is the distinctive CSL silhouette and aerodynamic benefit without the expense of a full carbon trunk replacement.

The integrated ducktail design increases rear aerodynamic stability by directing airflow cleanly over the rear deck while generating additional downforce over the rear axle. This design enhances the visual width and motorsport character of the G90 M5 while maintaining the refined proportions of the factory bodywork.

The spoiler is constructed from high-quality pre-preg carbon fiber using a classic 2x2 twill weave. Like many Alpha-N motorsport body components, the part is delivered in a raw carbon finish to allow professional body shop preparation and finishing. This manufacturing method prioritizes strength and minimal weight by avoiding heavy filler layers or excessive resin that would otherwise reduce structural integrity.

Notes

• This component ships in raw carbon fiber and requires professional body preparation and paint prior to installation
• The spoiler must be bonded and molded to the factory trunk lid by a professional body shop
• This component cannot be installed without the bonding and finishing process
• Alpha-N raw carbon body components prioritize structural strength and minimal weight and therefore do not include heavy filler layers or thick resin finishes
• Professional installation and finishing are required
• Motorsport/export component, road legality may vary by region and is the responsibility of the customer
• Designed and manufactured in Germany using high-quality carbon fiber materials
