DBA DBA4483XS Series Drilled Slotted Brake Rotor - 4000

The DBA DBA4483XS is a premium 4000 Series drilled and slotted brake rotor engineered by Disc Brakes Australia (DBA) for drivers who demand superior stopping power and thermal performance. Combining DBA's signature cross-drilling and Geomet® protective coating, this rotor is built to outperform standard OEM replacements in both everyday driving and demanding conditions.

DBA's 4000 Series XS (Xtreme Sports) rotors feature a unique combination of cross-drilled holes and curved slots machined into the rotor face. The cross-drilled holes reduce unsprung weight and aid in heat dissipation, while the curved slots continuously sweep the brake pad surface to remove gas, heat, and debris — keeping the pad-to-rotor contact zone clean and consistent for fade-resistant braking.

Key Features:

• Drilled & Slotted Design: Cross-drilled holes combined with curved slots for maximum heat dissipation and pad degassing
• Geomet® Corrosion Protection: Advanced zinc-based coating provides superior rust resistance compared to standard paint or uncoated rotors
• Thermal Stability: Enhanced heat handling reduces brake fade during repeated or aggressive stops
• Improved Bite & Response: Slotted surface continuously refreshes pad contact for consistent, confident braking feel
• Balanced Vane Technology: Internal vane design promotes optimal airflow through the rotor for continuous cooling
• OEM-Quality Fit: Direct bolt-on replacement with no modifications required
• DBA Manufacturing Standards: Produced to strict tolerances for minimal runout and vibration-free performance

The DBA 4000 XS Series is an ideal upgrade for performance-minded drivers seeking a significant improvement over stock rotors without the complexity of a full big-brake kit. Whether used on the street or on the track, the DBA4483XS delivers reliable, fade-resistant braking with long service life.
