The 3D Design G29 Z4 M40i Rear Diffuser enhances the rear fascia of BMW's G29 Z4 roadster with a purpose-built quad-outlet diffuser profile engineered around the M40i's performance exhaust configuration. The design frames the dual exit tips with structured diffuser elements that add visual depth and a motorsport-inspired presence to the Z4's rear end, complementing the roadster's dynamic character.

The 1x1 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.
