3D Design F8X M3 / M4 Carbon Rear Diffuser - Type 2

The 3D Design F8X M3 / M4 Rear Diffuser Type 2 offers a narrower, more restrained interpretation of the rear diffuser for the F80 M3 and F82 / F83 M4, providing a clean aero upgrade that emphasizes proportion over aggression. The Type 2 "narrow" design works in closer harmony with the factory rear bumper geometry, making it a natural complement to the M3's sedan roofline and the M4's coupe stance alike.

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.
