Carbon Side Skirt Extensions for BMW M3 G80 and G81 by Maxton Design

Transform your BMW M3 with premium carbon fibre sill extensions that deliver genuine motorsport presence and razor-sharp styling. Manufactured by Maxton Design’s dedicated carbon division, these rocker panel extensions bring an aggressive, OEM plus look while complementing the factory body lines for a clean, cohesive finish.

Engineered for a precise fit, these carbon side blades enhance stance, visually lower the car and tie together front and rear aero for a complete performance aesthetic.
