Upgrade the profile of your BMW 3 Series with premium carbon side skirt extensions

Give your G20 or G21 a sharper, lower and more purposeful stance with these 3DDesign carbon side blades. Engineered for the M Sport sill shape, they deliver an OEM plus look with the deep gloss and weave definition enthusiasts want. Ideal for drivers searching for BMW 3 Series side skirt extensions, G20 carbon side blades, G21 Touring rocker panel covers, carbon side sills, side splitters and M Sport aero kit upgrades.

Why enthusiasts choose this setup

• Precisely contoured for the M Sport rocker panels on G20 Saloon and G21 Touring, 2019 onwards including LCI.
• Real carbon fibre with a high-gloss finish for a premium, factory-style appearance.
• Neat, flush alignment that visually lowers the car and ties in with front splitters and rear diffusers.
