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.1,879.99Brand: Wilwood Part Number: 140-12876-R
Wilwood Engineering designs and manufactures high-performance disc brake systems. Since founding in 1977, we have developed a substantial matrix of brake components and engineering techniques that allow us to quickly and reliably create brake systems for almost any application. Their core ability is the rapid development of custom engineered brake systems using a combination of off-the-shelf and custom components. In addition to designing and manufacturing brakes for all types of competitive motor sports, Wilwood also manufactures brake systems and components for agricultural equipment, industrial applications, utility vehicles, snowmobiles, quads, motorcycles and military vehicles.
