The SQ-Aero Carbon Fiber Rear Diffuser was developed to complement the elegant yet performance-oriented character of the BMW G16 8 Series Gran Coupe. Designed to integrate seamlessly with the factory rear bumper, the diffuser adds greater visual depth and definition while preserving the sophisticated styling that defines BMW’s flagship four-door coupe.

Constructed from premium 200g twill carbon fiber, the SQ-Aero Rear Diffuser combines lightweight construction with exceptional durability and consistent weave quality. Its sculpted design enhances the rear profile of the vehicle, creating a more purposeful appearance that complements both factory and modified builds.

Each diffuser is finished with a high-gloss UV-resistant clear coat designed to protect the carbon fiber from fading, discoloration, and environmental exposure. The result is a durable finish that maintains its appearance through daily driving and long-term ownership.

Engineered specifically for the BMW G16 platform, the SQ-Aero Rear Diffuser follows the factory body lines for precise fitment and a factory-inspired appearance from every angle.
