BMW M4 G83 Convertible Carbon Fibre Rear Spoiler by 3D Design (2020+)

G83 M4 Cabriolet Boot Lip in Premium Carbon by 3DDesign Japan

Elevate the tail of your drop-top M4 with a genuine 3DDesign carbon boot lip spoiler crafted in Japan. This full-width decklid lip follows the sweep of the bootline and features a purposeful twin-fin centre profile inspired by CS styling for a sharper, more aggressive rear view. It is a subtle yet high-impact upgrade that looks factory plus and suits daily drivers and track toys alike.
