BMW G8X Carbon Fiber Outer Diffuser Trim

BMW G80 M3 / G82 G83 M4 Carbon Fiber Outer Diffuser Trim – by Luminous Carbon

Enhance the rear-end styling of your G8X with the Luminous Carbon Fiber Outer Diffuser Trim — the perfect finishing touch for your diffuser setup. Designed for the BMW G80 M3 and G82/G83 M4, this trim replaces the OEM gloss black surround with a bold carbon fiber upgrade that better complements your diffuser and other exterior carbon accents.

Crafted from authentic dry carbon fiber (pre-preg and autoclaved), this piece delivers lightweight strength and an ultra-premium feel. The 2x2 weave construction ensures a consistent look with other Luminous Carbon or OEM carbon parts. Each trim is finished with a UV-resistant clear coat to prevent yellowing and maintain a deep, rich finish over time.

This is a direct OEM replacement that installs using the same mounting points — no cutting, trimming, or permanent modifications required.
