BMW M3 Diffuser - Rear - Dinan - Carbon Rear Diffuser - Carbon Fiber - '21-'26. A carbon fiber upper diffuser surround that pairs with the OEM lower section for a clean, OEM+ rear profile.
Dinan’s design replaces only the upper surround, retaining the factory gloss-black lower so fit remains compatible with stock or personalized exhaust choices. Crafted from 2x2 gloss twill dry carbon (pre-preg) for strength and impact resistance, it uses factory mounting tabs for straightforward installation and a clean fit. A UV-stable clear coat helps resist fading. Pair with Dinan Rear Side Splitters for a cohesive rear look. Fitment: 2021–2026 BMW M3/M4 (G8X).
