DBA DBA4999XS Series Drilled Slotted Brake Rotor - 4000

The DBA DBA4999XS is a premium 4000 Series XS Drilled and Slotted brake rotor from Disc Brakes Australia (DBA), engineered for drivers who demand superior stopping performance under demanding street and light track conditions. DBA's 4000 Series XS rotors combine two proven performance technologies — cross-drilling and Uni-Directional slotting — into a single high-performance disc.

Key Features:

• Cross-Drilled Holes: Strategically placed drill holes allow heat, gas, and water to dissipate rapidly, reducing brake fade and improving wet-weather braking response
• Uni-Directional Slots (XS Pattern): DBA's exclusive curved slot pattern channels debris and gases away from the pad surface, maintaining consistent pad bite and extending pad life
• Enhanced Thermal Management: The combined drilled and slotted design dramatically improves heat handling compared to standard OEM rotors, keeping brake temperatures in a safe operating range during aggressive driving
• Premium Metallurgy: Manufactured from high-grade G3000 iron casting for consistent performance, minimal vibration, and long service life
• Zinc Dichromate Coating: Protective finish on non-friction surfaces resists corrosion and provides a clean, performance appearance straight out of the box
• OE-Quality Fit: Machined to precise OEM tolerances for a direct bolt-on installation with no modifications required
• Street and Track Capable: Designed for high-performance street use and light track day applications

The DBA 4000 Series XS rotor is a direct replacement upgrade over stock brake discs, delivering improved pedal feel, reduced brake fade, and enhanced durability. DBA is an ISO-certified manufacturer with decades of experience supplying OEM and performance brake components globally.
