2020-2025 C8 Corvette Performance Style Lower Diffuser Fins

The Corvette C8 Z51 Add-On Rear Lower Diffuser Fin is an aerodynamic device that is designed to improve the car's downforce by increasing the air pressure under the vehicle, thereby reducing lift and improving stability at high speeds. The rear lower diffuser fin is a single vertical fin that attaches to the lower edge of the rear diffuser, extending downward towards the road surface. This fin works together with the rear diffuser to create a low-pressure zone underneath the vehicle, which helps to pull the car down and reduce aerodynamic lift. The diffuser fin is made of lightweight ABS plastic, which helps reduce the overall weight of the vehicle and improve its performance.
