DBA DBA42677XD Series Cross-Drilled Dimpled Brake Rotor - 4000

The DBA DBA42677XD is a 4000 Series Cross-Drilled and Dimpled (XD) performance brake rotor from Disc Brakes Australia (DBA), engineered for BMW F-series platforms. Featuring DBA's signature Kangaroo Paw (KP) vane geometry, this rotor delivers superior thermal management and consistent stopping performance under both street and spirited driving conditions.

Key Features:

• 4000 XD Series: Combines cross-drilling and dimpling for maximum heat dissipation and gas/water evacuation at the pad-rotor interface
• Kangaroo Paw (KP) Vane Technology: Asymmetric curved vanes accelerate internal airflow, reducing rotor operating temperatures and minimizing brake fade
• Geomet Protective Coating: DBA's Geomet coating provides excellent corrosion resistance on the hat and non-swept areas, maintaining appearance and longevity
• Cross-Drilled Holes: Improve bite and pad degassing under heavy braking, reducing the risk of pad glazing
• Dimpled Surface: Adds additional surface area for cooling without compromising rotor structural integrity
• Direct OEM Replacement: Bolt-on fitment with no modifications required
• Made in Australia: Manufactured to strict DBA quality standards with OEM-grade metallurgy

The DBA42677XD is the right-side rotor, designed as a direct replacement upgrade over factory brake rotors. It is compatible with OEM and performance brake pad compounds and is an ideal upgrade for BMW enthusiasts seeking improved braking response, fade resistance, and a more aggressive rotor appearance.
