DBA DBA42806WXD 4000 Series Cross-Drilled & Dimpled Wave Front Brake Rotor

The DBA DBA42806WXD 4000 Series Cross-Drilled & Dimpled Wave Brake Rotor is a high-performance disc brake rotor engineered for drivers who demand superior stopping power and thermal management. Combining DBA's signature Geomet-coated Wave rotor profile with cross-drilled and dimpled venting, this rotor delivers exceptional fade resistance, consistent pedal feel, and extended service life under demanding driving conditions.

DBA's 4000 Series XD (Cross-Drilled & Dimpled) rotors feature a unique hole and dimple pattern that simultaneously evacuates heat, gas, and debris from the rotor surface. The alternating cross-drilled holes and dimples reduce unsprung weight while maintaining structural integrity, preventing the cracking that can occur with fully drilled-only designs. The proprietary Geomet protective coating on the hat and non-swept surfaces resists rust and corrosion, keeping the rotor looking and performing like new.

Key Features:

• 4000 Series XD Technology: Cross-drilled holes combined with dimples for maximum heat dissipation and gas evacuation
• Wave Rotor Profile: DBA's patented curved vane design increases airflow through the rotor core for reduced operating temperatures
• Geomet Coating: Corrosion-resistant surface treatment on non-contact areas extends rotor lifespan
• Improved Bite & Response: Enhanced initial bite and consistent braking performance across a wide temperature range
• Reduced Brake Fade: Superior thermal management minimizes fade during spirited or repeated heavy braking
• OE-Quality Fit: Manufactured to strict tolerances for direct OEM replacement with no modifications required
• Balanced Design: Computer-optimized hole and dimple placement ensures rotor balance and eliminates vibration

The DBA42806WXD is a front axle application rotor designed as a direct-fit replacement. DBA rotors are manufactured in Australia to ISO 9001 quality standards, making them a trusted upgrade over stock rotors for both street performance and occasional track use.
