Track spec rear diffuser made by Leg Motor Sport for ND (2016+) Mazda MX-5/Miata. In stock form the Miata has a lot of pockets where the flow off air is not consistent. With the rear diffuser by Leg Motor Sport, they flattened out everything from the differential to achieve smoother airflow through the underside of the car. This airflow has the benefit of creating downforce to stabilize the car through higher speeds as well as letting it cut through the air without any unnecessary drag. Great discreet way of adding downforce for those serious about track. Hybrid FRP is FRP (Unpainted) + small side pieces made of Carbon Fiber. Learn More
