Product Description
Diffusers work in conjunction with other aerodynamic components of a car to help produce downforce. Because a car displaces air as it moves forward, the air molecules in the rear of the car get disrupted, causing a vacuum of low-pressure air.
To help channel the high-speed air flow coming from underneath the car, diffusers redirect the high-speed air flow to transition smoothly into the low-pressure vacuum in the rear. This encourages a smoother flow of air underneath the car and allows for better performance from other aerodynamic components, such as aerodynamic wings.
