DBA 4000 series DBA42393 (2 pcs)

DBA 4000 Series HD Brake Rotors

The 4000 Series disc brake rotors are a direct replacement single-piece rotor designed for drivers who demand braking performance beyond standard OE levels.

The HD variant features a smooth OE-style rotor finish, making it ideal for drivers who want the benefits of the 4000 Series with an original equipment appearance—especially suitable for controlled race divisions.

Cast from high carbon alloyed iron and treated with DBA’s Thermal Stability Profiling (TSP), these rotors are engineered to withstand the heat and stress of repeated heavy braking.

DBA’s patented Kangaroo Paw ventilation system incorporates 144 diamond and teardrop-shaped pillars, delivering up to a 30% increase in surface area and a 20% improvement in cooling efficiency compared to traditional straight vane designs.
