Inspired by the GT3 RS, the AutoTecknic Roof Air Guide Fin Set is a precision-engineered upgrade designed to enhance both aerodynamics and aesthetics for the BMW G82 M4. Utilizing advanced 3D modeling, we’ve sculpted these fins to match the roof’s exact curvature, ensuring a seamless OEM-style fit. Crafted from pre-preg carbon fiber, they maintain an ultra-lightweight structure while delivering superior strength and durability. Their high-gloss carbon weave perfectly complements the M4’s factory carbon roof, creating a cohesive, motorsport-inspired look that turns heads both on and off the track.
Beyond aesthetics, these roof-mounted fins actively improve aerodynamic efficiency by directing hot air from the front middle radiator outward and away from the rear trunk, reducing drag and increasing downforce stability at high speeds. Whether you’re carving through canyon roads or dominating the track, this upgrade ensures maximum airflow management for enhanced performance. Elevate your G82 M4’s presence with a functional, race-inspired carbon fiber modification designed for passion-driven enthusiasts.
