DBA DBA42830 Series HD Slotted Brake Rotor - 4000 Front

The DBA DBA42830 is a 4000 Series Heavy-Duty (HD) brake rotor from Disc Brakes Australia, engineered for drivers who demand superior stopping performance and rotor longevity. Built on DBA's proven 4000 Series platform, this rotor features DBA's signature Geomet® protective coating to resist corrosion and extend service life beyond that of standard uncoated rotors.

DBA's 4000 Series HD rotors incorporate Kangaroo Paw (KP) internal vane technology, a unique bi-directional curved vane design that dramatically increases airflow through the rotor compared to conventional straight-vane rotors. This enhanced thermal management reduces brake fade and extends pad and rotor life under demanding driving conditions.

Key Features:

• Kangaroo Paw (KP) Vane Technology – Patented curved internal vanes increase cooling airflow for improved thermal performance
• Geomet® Corrosion Protection – Zinc-based coating provides long-lasting rust resistance on the hat and non-swept areas
• HD (Heavy Duty) Construction – Thicker, more durable casting designed for high-stress applications
• Street and Performance Use – Suitable for daily driving, spirited street use, and light track duty
• OE-Style Fit – Direct bolt-on replacement requiring no modification
• Precision Machined – Tight tolerances minimize runout and ensure smooth, vibration-free braking
• Meets or Exceeds OEM Specifications – Compatible with OEM brake hardware and calipers

The DBA42830 is a front brake rotor designed as a direct replacement, delivering the confidence of DBA's Australian-engineered braking technology.
