3D Design F32 / F36 4-Series M-Sport Carbon Rear Diffuser

The 3D Design F32 / F36 4-Series M-Sport Rear Diffuser brings a quad-tip aerodynamic panel to the lower rear section of both the BMW F32 Coupe and F36 Gran Coupe M-Sport, adding structured diffuser geometry and a comprehensive four-outlet exhaust framing that visually completes the rear bumper. Engineered for 435i and 440i specification with the M-Sport rear bumper, this diffuser upgrades the factory lower fascia with a performance-oriented appearance that remains proportionally appropriate for both body styles.

The quad-tip design precisely accommodates four exhaust outlets, ensuring a symmetrical, tailored appearance for 435i and 440i variants running quad-exit exhaust configurations. The 1x1 Carbon Fiber weave (CFRP) 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.
