DBA DBA43701XD 4000 XD Cross-Drilled & Dimpled Brake Rotor

The DBA DBA43701XD is a premium 4000 XD Series cross-drilled and dimpled brake rotor engineered for performance street and track use. Manufactured by Disc Brakes Australia (DBA), this rotor combines the gas-venting benefits of cross-drilling with the structural advantages of DBA's signature dimple pattern, resulting in a rotor that delivers consistent, fade-resistant braking performance under demanding conditions.

DBA's 4000 XD (Cross-Drilled/Dimpled) series represents the ideal balance between outright track performance and everyday street drivability. The cross-drilled holes allow gases and heat to escape from the rotor-pad interface, while the precision-machined dimples reduce unsprung weight and improve thermal dissipation without compromising rotor integrity. The combination reduces brake fade and improves wet-weather braking consistency.

Key Features:

• 4000 XD Series — DBA's performance cross-drilled and dimpled rotor design
• Precision cross-drilled holes for improved gas venting and heat dissipation
• Signature DBA dimple pattern for weight reduction and enhanced thermal performance
• Geomet® or zinc-flake coated hat and vane surfaces to resist corrosion
• Manufactured from premium G3000 grey iron for consistent friction and wear characteristics
• Computer-balanced for smooth, vibration-free operation
• Direct OEM-style fitment — no modifications required
• Designed for high-performance street and occasional track use

DBA rotors are manufactured in Australia to strict quality standards, making the DBA43701XD a trusted upgrade for drivers seeking improved braking performance over the factory rotor. This rotor is designed to pair with a wide range of performance brake pads and is compatible with the high-output braking demands of the 228kW FK-series chassis.
