Overview

The DBA 4000 Standard Rotors are disc brake rotors from DBA's 4000 Series HD variant. They feature a smooth OE style rotor finish, which is popular for drivers who want the benefits of a 4000 Series rotor but prefer an OE style look, such as for controlled race divisions. These rotors are cast from XG-150 high carbon alloyed iron and undergo Thermal Stability Profiling. This metallurgy allows them to handle increased stress and heat generated under intense braking. They feature DBA's patented Kangaroo Paw ventilation, which uses a series of 144 diamond and teardrop patterned pillars to achieve up to a 30% increase in surface area and a 20% improvement in cooling efficiency compared to traditional straight vane designs.
