Diffuser-Pro FRP Rear Underbody Panel

The RE Amemiya Diffuser-Pro is a specialized aerodynamic body panel designed specifically for the Mazda RX-7 FC3S chassis. This component addresses rear underbody airflow by utilizing an upswept, flat rear overhang profile. Integrated functional fins help manage air transition under the vehicle, contributing to improved aerodynamic performance. This unit is manufactured from durable fiber-reinforced plastic (FRP), balancing lightweight construction with the structural rigidity required for high-speed airflow environments. It is a direct-fitment application specifically engineered for all Mazda RX-7 FC3S models.
