DBA DBA42446XS Series Drilled Slotted Brake Rotor - 4000

The DBA DBA42446XS is a 4000 Series XS Drilled and Slotted brake rotor from Disc Brakes Australia, engineered for drivers who demand enhanced braking performance over standard OEM rotors. Combining cross-drilling and slotting in a single rotor, this disc delivers superior thermal management, consistent pedal feel, and improved bite under repeated heavy braking cycles.

Key Features:

• Cross-Drilled Holes: Promote rapid heat dissipation and help evacuate gases and water from the rotor surface, maintaining consistent braking performance
• XS Slotting Pattern: DBA's proprietary Xtra Strength (XS) slots are machined at a specific angle to sweep debris, water, and brake dust away from the pad surface for improved pad-to-rotor contact
• 4000 Series Construction: High-quality grey iron casting meets strict metallurgical standards for strength, durability, and thermal capacity
• Zinc Dichromate Coating: Corrosion-resistant finish on non-swept areas reduces rust and extends rotor service life
• Balanced Design: Each rotor is precision-machined and balanced to minimize vibration and brake pedal pulsation
• Direct OEM Replacement: Bolt-on fitment with no modifications required for applicable vehicles

The DBA 4000 Series XS is an ideal upgrade for performance street driving, towing, and spirited driving applications where stock rotors fall short. Manufactured by Disc Brakes Australia, a trusted name in performance braking with decades of motorsport heritage.
