DBA DBA42166XS 4000 Series Cross-Drilled & Slotted Front Brake Rotor

The DBA DBA42166XS is a 4000 Series Cross-Drilled and Slotted front brake rotor engineered for high-performance street and track applications. Featuring DBA's signature Kangaroo Paw (KP) vane geometry, this rotor delivers superior thermal efficiency and cooling performance over conventional straight-vane designs, helping maintain consistent brake feel under repeated hard stops.

The cross-drilled holes promote rapid gas and heat dissipation, while the slotted surface continuously sweeps the brake pad face to remove debris, glaze, and gas buildup — keeping the friction surface fresh and maximizing bite throughout the braking event.

Key Features:

• 4000 Series Cross-Drilled & Slotted: Combines the benefits of both surface treatments for maximum performance
• Kangaroo Paw (KP) Vane Design: Patented asymmetric vane geometry for enhanced airflow and heat dissipation
• Slotted Surface: Continuously cleans pad face and evacuates gases for consistent pedal feel
• Cross-Drilled Holes: Reduces rotor mass and promotes rapid heat venting
• DirectFit Design: Bolt-on replacement with no modifications required
• Premium Grade Iron: High-quality metallurgy for durability and fade resistance
• Electrophoretic (ED) Coat Finish: Factory-applied coating resists corrosion during storage and shipping

DBA rotors are engineered and manufactured in Australia to meet rigorous performance and quality standards. The DBA42166XS is a direct-fit front rotor replacement designed for the Ford Mustang GT (2015 and newer), making it an ideal upgrade for enthusiasts seeking improved braking performance over the factory rotor.
