3DDesign Carbon Fibre Side Skirts For BMW 5 Series M Sport (2017-2023, G30 G31)

3DDesign carbon fibre sill extensions for BMW 5 Series G30 G31 M Sport

Transform the profile of your BMW 5 Series with 3DDesign’s premium carbon fibre sill extensions. Engineered specifically for G30 saloon and G31 estate models with the M Sport package, these rocker panel additions deliver a lower, wider look and a purposeful OEM-plus finish. Expect precise fitment, beautiful carbon construction and a true premium upgrade that ties the whole body styling together.

We have fitted these on customer cars and the feedback has been excellent. The visual drop along the lower edge sharpens the stance instantly, elevating everyday road presence while complementing factory M Sport lines. If you are building a cohesive aero package with a front splitter and rear diffuser, these side blades are the missing piece.

Why enthusiasts choose this upgrade

• Vehicle-specific aero for G30 and G31 M Sport models for a clean, factory-style interface
• Premium carbon fibre construction for strength, rigidity and a high-end appearance
• Supplied with a fitting kit to support secure installation
• Enhances the lower silhouette for a sportier, more aggressive look
• Genuine 3DDesign quality trusted by BMW owners worldwide
