3D Design F8X M3 / M4 Dry Carbon Rear Diffuser - Type 1

The 3D Design F8X M3 / M4 Rear Diffuser Type 1 delivers a bold, full-width rear aero upgrade for the F80 M3 and F82 / F83 M4, integrating seamlessly with the factory rear bumper to provide a more structured, motorsport-influenced lower rear fascia. The Type 1 design offers the wider, more comprehensive diffuser profile in the 3D Design F8X lineup, making it the definitive aero upgrade for owners who want maximum rear visual impact with OEM-level build quality.

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.
