Enhance the rear decklid profile and aerodynamic stability of your BMW 4 Series Gran Coupé or i4 with the authentic 3DDesign Carbon Fiber Trunk Spoiler. Engineered specifically for the BMW G26 Gran Coupé platform (compatible with M-Sport models including M440i and i4 M50), this trunk spoiler adds an aggressive, sporty lip extension to the rear tailgate line—especially when paired with a rear diffuser.
Crafted from ultra-lightweight dry carbon fiber featuring a classic 2x2 weave pattern and high-gloss clear coat finish, it ensures maximum structural rigidity without adding unnecessary weight. The trunk spoiler attaches easily and securely to the rear trunk lid using pre-applied heavy-duty double-sided tape alongside supplied mounting hardware.
An essential exterior upgrade for BMW G26 owners seeking genuine Japanese dry carbon craftsmanship and flawless OEM-plus fitment.
