Show original supplier description
The 3D Design G30 5-Series Carbon Rear Diffuser—Type 1 is crafted to provide a refined aerodynamic enhancement to the lower rear section of the BMW G30 5-Series. It introduces a structured diffuser profile, adding visual depth and rear-end presence specifically for models equipped with the M-Sport Package. The Type 1 design integrates seamlessly with the factory M-Sport bumper's geometry, acting as a natural extension of the vehicle's existing design language. Constructed from a 1x1 Carbon Fiber weave (CFRP) and finished with a gloss clearcoat, this rear diffuser is designed for direct mounting to the factory M-Sport rear bumper. This ensures a factory-quality installation process without requiring permanent modifications. The use of carbon fiber not only keeps the upgrade lightweight but also provides a premium aesthetic that visually distinguishes the G30. Designed and manufactured in Japan, 3D Design components are known for their precision fitment, durability, and real-world usability, blending motorsport influence with street functionality. This rear diffuser includes all necessary installation hardware and instructions. It is important to note that this diffuser requires the factory M-Sport Package and is not compatible with non-M-Sport G30 5-Series trims.
