DBA DBA53146.1XD Series Cross-Drilled Dimpled Brake Rotor with NAS Nuts - 5000

The DBA DBA53146.1XD is a 5000 Series XD (Cross-Drilled & Dimpled) performance brake rotor engineered for drivers who demand superior stopping power and thermal management. Manufactured by Disc Brakes Australia (DBA), this front rotor is designed for high-performance applications and features DBA's signature cross-drilled and dimpled surface pattern for maximum brake pad bite and heat dissipation.

DBA's 5000 Series XD rotors combine two proven technologies: cross-drilling promotes rapid cooling and gas/dust evacuation, while the dimpled (or "Kangaroo Paw" KP) pattern provides additional bite zones without compromising rotor integrity. The result is consistent, fade-resistant braking performance under both street and track conditions.

Key Features:

• Cross-Drilled & Dimpled (XD) Surface: Combines drilled holes with KP dimples for enhanced heat dissipation, pad degassing, and improved wet-weather performance
• NAS Nuts Included: Supplied with NAS (National Aerospace Standard) locking nuts for secure, rattle-free installation
• Kangaroo Paw (KP) Venting Technology: Curved internal vanes promote airflow through the rotor for consistent thermal management
• Premium Grade Iron: Manufactured from high-grade iron alloy for durability and long service life
• Protective Coating: Non-braking surfaces feature corrosion-resistant coating to prevent rust and maintain appearance
• OEM-Style Direct Fit: Engineered as a direct bolt-on replacement requiring no modifications
• Balanced & Ready to Install: Each rotor is precision-balanced and tested before leaving the factory

The DBA 5000 Series XD is the ideal upgrade for enthusiasts seeking measurable improvements in braking performance over standard OEM rotors. Packaged complete with NAS locking nuts, this rotor delivers everything needed for a straightforward installation.
