DBA DBA43340XD 4000 Series XD Cross-Drilled & Dimpled Front Brake Rotor

The DBA DBA43340XD is a high-performance front brake rotor from DBA's (Disc Brakes Australia) 4000 Series XD lineup, featuring a patented cross-drilled and dimpled surface design engineered for improved braking performance over standard OEM rotors.

The XD (cross-drilled and dimpled) surface pattern provides multiple performance benefits: cross-drilling promotes rapid heat dissipation and gas evacuation under hard braking, while the dimple pattern adds structural integrity to prevent cracking that can occur with fully drilled rotors alone. The result is a rotor that runs cooler, bites harder, and lasts longer under demanding driving conditions.

Key Features:

• 4000 Series XD design — patented cross-drilled and dimpled rotor surface for superior heat dissipation and bite
• Kangaroo Paw (KP) venting — DBA's proprietary internal vane geometry for optimized airflow and reduced operating temperatures
• Thermally stable — precision-balanced construction minimizes vibration and pedal pulsation
• Street and performance use — suitable for spirited street driving, track days, and high-demand daily use
• Direct OEM replacement — bolt-on fitment, no modifications required
• Premium grade iron — high-carbon alloy construction for durability and consistent performance

Manufactured in Australia to stringent quality standards, the DBA 4000 Series XD rotors are a trusted upgrade for drivers seeking improved stopping power and thermal management over factory brake components.
