The DBA Smooth-Plain 4000 Brake Rotor is a direct replacement single-piece rotor designed for drivers who want better braking performance. The rotationally balanced design of the Smooth-Plain 4000 provides smoother and more efficient braking action, while the high carbon alloyed iron castings provide superior strength and durability. The unique Kangaroo Paw ventilation system uses 144 diamond-and-teardrop-shaped pillars to enhance the surface area for more effective cooling. The DBA Smooth-Plain 4000 Brake Rotor is the ideal choice for drivers who demand the best in braking performance and durability.
DBA's 4000 Series disc brake rotors are direct replacement single-piece rotors designed for drivers wanting better braking performance. DBA's metallurgy, cast from XG-150 high carbon alloyed iron and thermally profiled, can endure greater stress and heat under intensive braking applications. DBA's proprietary Kangaroo Paw ventilation uses 144 diamond-and-teardrop-shaped pillars to enhance the surface area by 30% and cooling effectiveness by 20%. (as compared to a traditional straight vane design). Available with OE style CBN finish, XD cross drilled (XD)*, or DBA's proprietary T3 tri-symmetrical (S) slot design.
