CT Design carbon sill extensions for BMW F40 hatchback
Give your F40 a sharper, lower and more purposeful stance with these premium CT Design carbon sill extensions. Crafted from high quality pre-preg carbon, this upgrade delivers lightweight strength, crisp fitment and a clean motorsport look that suits the latest 1er perfectly.
