Transform the rear profile of your BMW F90 M5 or M5 Competition with this 3D Style Carbon Fiber Rear Diffuser. Designed to replace the factory diffuser, this aggressive three-piece design enhances the vehicle’s motorsport-inspired appearance while perfectly complementing the M5’s muscular body lines.
Crafted from high-quality 2×2 carbon fiber weave, the diffuser features a deep gloss clear coat finish that seamlessly matches other carbon fiber components and OEM styling elements. A durable UV-resistant protective coating helps guard against fading, discoloration, road debris, and harsh environmental conditions, ensuring a lasting showroom-quality appearance.
Engineered for precise fitment, the diffuser mounts securely in place of the factory unit and requires rear bumper removal for installation. Combining striking aesthetics, premium materials, and exceptional durability, this rear diffuser is the perfect upgrade for enthusiasts looking to elevate the appearance of their F90 M5.
