3D Design G14 / G15 8-Series Carbon Rear Diffuser
The 3D Design G14 / G15 8-Series Rear Diffuser enhances the factory M-Sport rear bumper of BMW's grand touring coupe lineup with a structured, aerodynamically intentional element that completes the lower rear visual profile. Engineered to integrate with the OEM M-Sport rear bumper geometry, this diffuser adds symmetry and depth to the rear end of the G14 Convertible and G15 Coupe, elevating the overall presentation with a more purposeful, track-influenced appearance.
The 2x2 pre-preg carbon fiber construction delivers a gloss clearcoat finish that highlights the weave beneath, with OEM-level surface texture and consistent factory-style fitment.
Designed and manufactured in Japan, 3D Design components are developed with a focus on fitment precision, durability, and real-world usability. Their approach blends motorsport influence with street functionality, resulting in aerodynamic upgrades that enhance both form and function without sacrificing practicality.
