DBA DBA53940.1XD Series Cross-Drilled Dimpled Brake Rotor with NAS Nuts - 5000 Front

The DBA DBA53940.1XD is a 5000 Series XD (Cross-Drilled & Dimpled) performance brake rotor engineered for demanding street and track use. Part of DBA's flagship 5000 Series lineup, this rotor combines cross-drilled holes with dimpled slots to deliver superior heat dissipation, enhanced bite, and consistent braking performance under extreme conditions. This unit includes NAS (National Aerospace Standard) nuts for secure hat-to-rotor fastening.

Key Features:

• 5000 Series XD Technology: Cross-drilled holes and dimpled slots work together to evacuate heat, gas, and debris from the rotor face, maintaining pedal feel and reducing fade
• Kangaroo Paw (KP) Ventilation: DBA's patented Kangaroo Paw internal vane technology promotes superior airflow through the rotor for faster thermal cooling
• NAS Nuts Included: National Aerospace Standard hardware ensures a precise, rattle-free connection between the hat and rotor disc
• Two-Piece Floating Design: The separate aluminum hat and rotor disc allow for thermal expansion and reduce heat transfer to the hub and wheel bearing
• Rust-Inhibiting Coating: Non-directional rotor finish with protective coating on non-swept surfaces to resist corrosion during storage and service
• Direct OEM Replacement Fitment: Engineered to bolt on without modification using factory mounting points
• Made in Australia: Manufactured to DBA's strict quality and metallurgical standards

The DBA 53940.1XD is a front axle rotor designed for the Chevrolet Camaro ZL1 (2019 and newer). Whether pushing hard on a road course or demanding reliable stops in daily performance driving, this rotor delivers the thermal capacity and braking consistency expected from DBA's 5000 Series line.
