BMW G90 G99 M5 M5 Touring MP Style Real Carbon Fiber Rear Bumper Diffuser Valance 2025-2026

Upgrade the rear-end appearance of your 2025-2026 BMW G90 M5 Sedan or G99 M5 Touring with this MP Style Real Carbon Fiber Rear Bumper Diffuser Valance. Designed for compatible M5 models, this rear bumper upgrade features an aggressive shark-fin-inspired design that complements the bold styling of the latest BMW M5 generation.

Constructed from genuine carbon fiber with a protective clear-coated finish, the MP Style diffuser features a distinctive aerodynamic-inspired profile and exposed carbon fiber appearance. The sculpted design enhances the lower rear bumper and complements the factory quad-exhaust layout, creating a sportier, more refined rear-end look for both the M5 Sedan and M5 Touring.

Designed as a direct replacement for compatible factory rear diffuser components, this two-piece carbon fiber kit mounts to the lower rear bumper using a bolt-on attachment method. Mounting hardware is included for installation. Professional installation is recommended to ensure proper alignment, secure attachment, and clearance around the exhaust outlets and surrounding bumper components.
