3D Design G02 X4 M40i Carbon Rear Diffuser
AVAILABLE TO ORDER
The 3D Design G02 X4 M40i Rear Diffuser enhances the factory rear bumper with a purpose-built four-tip diffuser design tailored to the M40i's quad-exit exhaust layout. Rather than imposing a purely race-inspired aesthetic, 3D Design focuses on proportional integration — the diffuser extends the lower bumper profile with structured fins and exhaust apertures that frame the factory tips and add visual depth to the rear end.
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.
