The DBA 4000 Series XS is a high-performance rear brake rotor engineered for drivers who require superior thermal management and consistent braking response. This rotor (MPN DBA42663XS-10) is cast from high carbon, heat-treated iron to withstand the intense thermal stress of spirited driving or heavy braking cycles. The XS design features a non-directional cross-drilled and slotted pattern that helps degas brake pads, increases initial bite, and maintains a clean friction surface for reliable performance in both wet and dry conditions.

Key to the 4000 Series' cooling capability is the patented Kangaroo Paw ventilation system. Unlike traditional straight-vane rotors, this design utilizes a series of 144 diamond and teardrop-shaped pillars to increase surface area and maximize airflow, ensuring faster heat dissipation and reduced brake fade. As a direct replacement rotor, it bolts onto the factory mounting points without the need for modifications.
