3D Design G05 X5 Carbon Rear Diffuser Side Extension Set

The 3D Design G05 X5 Carbon Rear Diffuser Side Extension Set provides the finishing touch to 3D Design's rear aero suite for the G05 X5, flanking the central diffuser with carbon side garnishes that extend the visual width and aerodynamic language of the rear bumper. Designed for M-Sport and M50i equipped models, these extensions integrate with 3D Design's G05 rear diffuser to deliver a complete, cohesive lower rear treatment that enhances the commanding proportions of the X5 without becoming visually overwrought.

Constructed from 1x1 Carbon Fiber weave (CFRP) with a gloss clearcoat finish, each side extension pairs with the central carbon diffuser to create a unified rear end presentation. The side extensions are sold as a set and designed specifically as add-on components to the 3D Design G05 X5 Carbon Rear Diffuser — they do not include the center diffuser section.

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.
