Full Carbon Rear Diffuser to Give the BMW 8 Series G15 a More Aggressive Rear Profile
Designed for selected BMW 8 Series G15 840i and M850i M Sport Coupé (2020–2022) models, this carbon fiber rear diffuser replaces the original lower rear bumper section with a sharper and more aggressive performance-inspired design. The vehicle-specific profile follows the factory M Sport bumper contours for clean OEM+ fitment while adding deeper diffuser fins and a more distinctive rear-end appearance.
Made from dry carbon fiber with a 3x3 twill carbon fiber weave, UV-protected clear coating and a shiny gloss carbon finish, this rear diffuser combines lightweight construction with a premium visible carbon appearance. The sculpted lower section and integrated exhaust openings complement the wide rear profile of the G15 while pairing naturally with other carbon fiber exterior upgrades.
Self-tapping screws are included for secure installation. The direct replacement design is shaped specifically for the factory M Sport rear bumper and installs after removal of the original lower diffuser section. Professional installation is recommended for correct alignment, exhaust clearance, secure mounting and long-term durability.
