Questions and Answers

BJ's Garage 570,  2008-2017 Dodge Challenger, Defender Series Comp Diffuser

Made from 3003 Aluminum, Etched and Painted Matte Black. The Science: The Defender Series Comp Diffuser will improve your car's aerodynamic properties by enhancing the transition between the high-velocity airflow underneath the car and the much slower freestream airflow of the ambient atmosphere. This diffuser acts as an expansion chamber to manage the air as it exits from underneath the car and reintegrates it with higher-pressure ambient air. Smoothing this transition reduces turbulence and drag in the vehicle's wake and improves airflow under the vehicle.The laws of fluid dynamics state that as the velocity of air increases, its pressure decreases. An F1 car is low to the road, and thus its flat bottom acts as a venturi to pinch the air and force it to move faster relative to the air above the car. This pressure differential manifests as increased load on the tires and sucks the car closer to the road providing a more stable environment in Higher Speed Applications.
