DBA DBA42000XS 4000 Series XS Gold Drilled & Slotted Performance Brake Rotor

The DBA DBA42000XS 4000 Series XS Gold is a direct-replacement, single-piece drilled and slotted performance brake rotor engineered for drivers seeking a significant upgrade over standard OE braking. Cast from XG-150 high carbon alloyed iron and treated with DBA's proprietary Thermal Stability Profiling (TSP) process, this rotor is built to handle the intense heat and mechanical stress of demanding performance driving applications.

The XS Gold surface design combines cross-drilled holes with symmetrical slotting to maximize the exit points for brake pad friction dust and gases, delivering cleaner, more consistent braking response and a quieter pedal feel. The symmetrical, non-directional pattern allows for universal left/right fitment, simplifying installation.

Key Features:

• XG-150 High Carbon Alloyed Iron construction for superior strength and thermal capacity
• Thermal Stability Profiling (TSP) — heat treatment cycles realign the iron microstructure for maximum rotor stability and reduced metal fatigue
• Kangaroo Paw Vane Technology — 144 diamond and teardrop-patterned internal pillars deliver up to 30% more surface area and 20% greater cooling efficiency versus traditional straight-vane designs
• Cross-Drilled & Slotted Surface — increases exit points for friction dust and gases, improving bite and pedal response
• Symmetrical / Bi-Directional Design — universal left/right fitment; no directional confusion during installation
• Thermographic Heat Paint (TGHP) — color-changing paint markings indicate temperature thresholds, helping monitor rotor fatigue and guide brake pad selection
• CBN Machine-Turned Finish — Cubic Boron Nitride surface machining minimizes disc thickness variation to reduce pad knock and premature wear
• Anti-Rust Coating — non-friction areas are painted to resist corrosion and enhance appearance
• Direct OE replacement fit — no modifications required

The 4000 Series XS Gold is an excellent choice for performance street driving and show vehicles seeking the premium aesthetics of a cross-drilled rotor combined with proven high-carbon construction. Note: Drilled rotor configurations are not recommended for heavy off-road or dedicated track day use.
