$2,995.00

The 3D Design G8X M3 / M4 Carbon Rear Diffuser brings a focused, motorsport-derived aesthetic to the factory rear bumper of the G80 M3 and G82 M4, completing the lower rear fascia with a clean, purposeful carbon structure. 3D Design's diffuser design prioritizes OEM-level integration and proportion, ensuring the upgrade feels like a natural extension of the G8X's existing design rather than a bolt-on afterthought.

Constructed from 2x2 pre-preg carbon fiber with a gloss clearcoat finish, the Rear Diffuser installs directly to the factory rear bumper assembly with no cutting or permanent modification required. The precision-engineered profile frames the quad exhaust outlets cleanly, adding visual structure to the lower rear and reinforcing the performance character of both the M3 and M4 variants.

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.
