Proper air ducting is critical for effective performance of short track stock car disc brake systems. Faster cars, improved tires and better aerodynamics has changed the design requirements for brake ducting. Short tracks and most road courses require specific air duct considerations to maximize the brake systems effectiveness.
Channeling sufficient air from the front of the car through the front brakes is required to remove the large amounts of heat generated by severe and prolonged brake use. An efficient air ducting system can prevent brake system overheating and greatly improve pad life. As car designs have evolved, the aerodynamics of the car’s front end has changed, thereby affecting the air flow entering the front air scoops (plenum). Because of this change in air flow, the positioning of intake plenums should be re-evaluated.1,594.99Brand: Wilwood Part Number: 140-12878-D
