Basic Carbon BMW F90 M5 Carbon Fibre Side Skirts - Gloss OEM-Style Side Skirt Extensions (2016-2019) BC99875

BC99875 BMW F90 M5 Carbon Side Sill Extensions by Basic Carbon

Give your BMW F90 M5 a sharper, lower and wider look with these gloss carbon side sill extensions. This premium rocker panel upgrade delivers a factory-look finish with a performance edge, completing the profile of the M5 and tying in perfectly with other exterior carbon accents. Lightweight, strong and designed for vehicle-specific alignment, they look right at home on the F90.

Each piece is hand laid in real carbon fibre and finished with a deep, high-shine clear coat for long-lasting gloss and easy maintenance. The fit is dialled in for the F90 chassis so the lines sit flush with the body, enhancing the silhouette without fuss. The result is a clean, motorsport-inspired side blade that adds serious kerb appeal.

• Vehicle-specific alignment for a clean, factory-look install
• Hand laid carbon fibre with a polished gloss finish
