RKP Composites Carbon Fibre/Carbon Fiber Side Skirts/Rocker Panel Extensions for BMW M4 F82/F83 (Coupe & Convertible) - OEM+ 2x2 Weave, Vacuum Infused - Pair, Made in USA

RKP Composites Carbon Fibre Side Skirt Extensions for BMW M4 F82 F83

Give your M4 the stance it deserves with genuine RKP Composites lower rocker extensions. Designed around the F82 coupe and F83 convertible platform, these carbon sill blades add purposeful width, clean OEM-like lines and a true motorsport vibe without looking overdone. If you are searching for stylish side aero for your F8x, this is the premium choice.

Crafted in the USA using a vacuum infusion process, each piece achieves an excellent carbon-to-resin ratio for superb rigidity and long-term durability. The consistent 2x2 twill pattern delivers a uniform, directional weave that aligns beautifully from front to rear for a factory-plus finish. Fitment is dialled-in by RKP for a precise interface with the original rocker trims.

We have installed these on customer cars at MJ Modifications and on our own builds. Feedback is consistently positive - precise fit, top-tier carbon quality and a transformation in side profile that makes the M4 look lower, sharper and more aggressive while still retaining a refined, factory aesthetic.
