COOL BRAKE ROTOR DESIGNS Greater clamping force also generates more heat. To combat this, racing brake rotor designs have improved to dissipate heat faster and promote better brake pad wear that will last during a 500 or 1000 mile course. In an effort to find new materials for rotors to run cooler, Racing brake manufacturers have experimented with ceramic and carbon fiber materials in other racing applications like Formula-1 and road racing. Through testing, however, Brembo engineers found that the carbon material does not like the mud, dirt, water and rocks. According to their experiences, the variables of off-road racing such as hill climbing, silt, mud, rain and heat, cause significant wear to carbon brake rotors, thus reducing performance in this instance. ยจ The result is in off-road racing, more durable iron rotors are used, but feature improved internal designs with air ducts and exterior metal coatings that have proven to be very successful in reducing heat and wear. "Our rotor castings are developed specifically for off-road racing and feature details such as turbulator vane technology, which uses ridged vanes to disturb the airflow through the disc for improved cooling," says Hargreaves. "Alcon has also developed a floating drive system for off-road products, which allows the disc and bell to float more freely and independently of each other, reducing the risk of cracking and allowing the rotors to run truer through the rigors of off-road UNLIMITED TROPHY TRUCKS LIKE THIS VOSS MOTORSPORTS TRUCK, USES THE LATEST HIGH- PERFORMANCE SIX-PISTON CALIPER AND ROTOR DESIGN TECHNOLOGY TO RUN COOLER AND MAINTAIN BRAKING POWER THROUGHOUT A FULL RACE. - STOPTECH'S STO-60 OFF-ROAD RACING CALIPER SHOWS A TOP STIFFENING BRIDGE THAT HELPS KEEP THE CALIPER RIGID.
