BMW 3 Series F30 F31 Side Skirts/Skirt Extensions – Gloss Carbon Fibre M Performance/MP Style | Rock

Carbon rocker extensions for BMW 3 Series F30 and F31

Give your saloon or touring a sharper, lower stance with gloss carbon sill extensions that add instant road presence. These motorsport‑inspired side blades are built from real carbon fibre with a deep, mirror‑like clear coat, transforming the profile of your 2012 to 2018 3 Series with an aggressive OEM+ look.

Why enthusiasts choose these rocker extensions

• Real carbon construction throughout for a premium appearance and lightweight rigidity
• Deep gloss clear coat for a rich, high‑shine finish that pairs perfectly with other aero upgrades
• Precision moulded for neat, consistent fitment on F30 saloon and F31 touring models
• Subtle yet assertive styling that visually lowers the car and complements front splitters and rear diffusers
• Excellent value upgrade that delivers a genuine performance aesthetic without the dealer price tag
