The Mugen FL5 Group B Carbon Fiber Side Spoiler Set is a core component of the "Extreme R" aerodynamic philosophy, engineered to provide a seamless transition of downforce from the front splitter to the rear diffuser. These spoilers feature a prominent protrusion design that meticulously manages airflow along the vehicle’s flanks, reducing turbulence and increasing high-speed stability. The aesthetic is directly inspired by competitive racing, with a sharp, aggressive silhouette that connects the fin-shaped front bumper garnish to the rear of the car, creating a cohesive sharp side profile.

Beyond their visual impact, these side spoilers prioritize significant performance gains through advanced material engineering. Constructed from high-quality Carbon Fiber Reinforced Plastic (CFRP), this set achieves a weight reduction of approximately 2.0 kg compared to the factory units. Functionally, the spoilers sit 24.5mm lower than the standard components, effectively sealing the side of the chassis to enhance the ground-effect characteristics of the FL5. This set is a vital upgrade for the track-focused enthusiast looking to achieve the perfect balance of lightweight construction and aerodynamic precision.
