DBA DBA42830WXD Series Cross-Drilled Slotted Wave Brake Rotor - 4000

The DBA DBA42830WXD is a 4000 Series XD Cross-Drilled and Slotted Wave Brake Rotor from Disc Brakes Australia, engineered for performance street and light track use. Combining DBA's signature Wave rotor profile with cross-drilled holes and directional slots, this rotor delivers superior heat dissipation, improved bite, and consistent braking performance under demanding conditions.

DBA's 4000 Series XD rotors feature a unique wave-edged rotor face that continuously sweeps the brake pad surface to remove debris and gases, maintaining a clean contact patch for maximum stopping power. The cross-drilling further aids in cooling and reduces unsprung weight, while the slots channel away heat, water, and brake dust for reliable, fade-resistant performance.

Key Features:

• Wave Rotor Profile: DBA's proprietary scalloped outer edge continuously cleans the pad surface for consistent bite
• Cross-Drilled & Slotted (XD): Promotes rapid heat dissipation and prevents brake fade during spirited driving
• 4000 Series Construction: Premium metallurgy for durability and thermal stability
• Kangaroo Paw Venting: Advanced internal vane design for enhanced airflow and cooling efficiency
• Electrophoretic (E-coat) Finish: Corrosion-resistant coating on non-friction surfaces for long service life
• Direct OEM Replacement: Bolt-on fitment with no modifications required
• Street and Performance Use: Ideal for high-performance street driving and light track day use

Manufactured in Australia to strict quality standards, DBA 4000 Series XD Wave rotors are a direct-fit upgrade over standard rotors, providing a noticeable improvement in braking feel and thermal performance. Each rotor is individually packaged and ready for installation.
