DBA DBA42281SLVXD Series XD Drilled Dimpled Performance Brake Rotor - 4000

The DBA DBA42281SLVXD is a 4000 Series XD performance disc brake rotor from Disc Brakes Australia (DBA), engineered as a direct-fit, single-piece replacement for drivers seeking braking performance well above standard OE levels. The XD designation identifies this rotor's signature non-directional cross-drilled and dimpled surface finish, delivering enhanced cooling and a bold sports appearance.

XD Drilled & Dimpled Design:

• Non-directional cross-drilled and dimpled pattern — DBA's unique combination of drilled holes and dimples provides superior structural support compared to traditional fully drilled rotors, reducing the risk of cracking under stress
• Chamfered drill holes facilitate efficient evacuation of friction dust and gases, contributing to a quieter, more responsive brake pedal feel
• Symmetrical drilling pattern allows universal left/right fitment
• Painted non-friction surfaces resist rust and enhance visual appeal
• Note: Drilled rotor configurations are not recommended for heavy off-road or track day use

4000 Series Construction & Technology:

• Cast from XG-150 high carbon alloyed iron for superior strength, heat resistance, and long rotor life
• Thermal Stability Profiling (TSP) — DBA's proprietary heat treatment process subjects the iron to controlled heat cycles, relieving internal manufacturing stresses and maximizing thermal stability and fatigue resistance in demanding applications
• Kangaroo Paw ventilation system — DBA's patented internal vane design features 144 diamond and teardrop-shaped pillars, delivering up to 30% more surface area and 20% better cooling efficiency versus conventional straight-vane designs
• Thermo-Graphic Heat Paint (TGHP) — color-changing paint markings on the rotor's outer edge shift at specific temperature thresholds, allowing drivers to monitor peak braking temperatures and rotor fatigue
• Centre split core castings for increased heat transfer and thermal efficiency

The DBA 4000 Series XD rotor is backed by DBA's commitment to quality and is a proven upgrade for performance-oriented street driving, delivering consistent, fade-resistant stopping power with every application.
