The 3D Design G90 / G99 M5 Carbon Fiber Rear Diffuser sets a new benchmark for carbon aero fitment on BMW's latest M5 platform, delivering a clean OEM+ rear aesthetic with a motorsport-caliber finish for both the G90 M5 Sedan and G99 M5 Touring. Built on 3D Design's established legacy of high-quality M5 aero development, this diffuser brings the same level of engineering precision and surface quality to the new-generation M5 that made their previous-generation packages a benchmark in the aftermarket.
Constructed from pre-preg carbon fiber with a gloss clearcoat finish, the diffuser features side fins that flow naturally with the factory rear bumper contours, adding depth and presence without overpowering BMW's original design intent. The design includes a full carbon fiber replacement tow hook cover for a complete, uncompromised finish. Installation utilizes factory-style mounting clips, ensuring a secure fitment with no permanent modification to the factory bumper assembly.
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.
