DBA DBA42439XS Series Drilled Slotted Brake Rotor - 4000

The DBA DBA42439XS is a 4000 Series Cross-Drilled and Slotted brake rotor from Disc Brakes Australia (DBA), engineered for drivers who demand superior stopping performance over the factory rotor. Combining cross-drilling and slotting in a single rotor, this disc delivers improved thermal management, better bite, and consistent fade-free braking under demanding conditions.

Key Features:

• Cross-Drilled & Slotted Design: Drill holes and slots work together to evacuate heat, gas, and brake dust from the rotor face, maintaining firm, consistent pedal feel
• 4000 Series Construction: DBA's entry-level performance rotor line, manufactured to meet or exceed OEM dimensional specifications for a direct-fit replacement
• Improved Thermal Performance: Enhanced heat dissipation reduces brake fade during repeated or aggressive stops, ideal for spirited street driving and light track use
• Zinc Dichromate Coating: Corrosion-resistant coating on non-swept surfaces helps prevent rust and maintains a clean appearance under the wheel
• Kangaroo Paw Venting: DBA's patented internal vane geometry promotes increased airflow through the rotor for cooler running temperatures
• Direct OEM Replacement: Designed as a bolt-on upgrade requiring no modification for compatible vehicles
• Manufactured in Australia: DBA rotors are produced to strict quality standards at their Australian facility

The DBA 4000 Series XS rotor is an excellent upgrade from a standard smooth rotor for enthusiast drivers looking for stronger, more responsive braking on the street. It is compatible with a wide range of performance brake pad compounds and requires no special break-in beyond normal bedding procedures.
