4000 Series disc brake rotors are a direct replacement single piece brake rotor, designed for drivers seeking upgraded braking above and beyond standard OE levels.
4000 Series HD features a smooth OE style rotor finish, popular for drivers looking for the benefits of a 4000 Series rotor but requiring an OE style look, such as controlled race divisions.
Cast from high carbon alloyed iron and undergoing Thermal Stability Profiling, DBA’s metallurgy can handle the increased stress and heat generated under intense braking applications, time and time again.
Featuring DBA’s Kangaroo Paw ventilation that implements a series of 144 diamond and teardrop patterned pillars, DBA achieves up to a 30% increase in surface area and 20% improvement in cooling efficiency (as compared to a traditional straight vane design).
