DBA DBA42968XS 4000 Series XS Cross-Drilled & Slotted Front Disc Brake Rotor

The DBA DBA42968XS is a 4000 Series XS cross-drilled and slotted front disc brake rotor engineered for high-performance street driving. Built by Disc Brakes Australia (DBA), a globally recognized leader in brake rotor technology, this rotor combines premium materials and advanced manufacturing processes to deliver confident, fade-resistant stopping power above and beyond OEM levels.

The XS surface design features a non-directional cross-drilled and slotted pattern that increases the number of exit points for brake pad friction dust and gases, resulting in a cleaner, more responsive pedal feel. The symmetrical drill and slot layout makes this rotor bi-directional, offering universal left/right fitment with no additional parts required.

Key Features:

• High-Carbon Alloyed Iron Construction: Cast from XG-150 high-carbon alloy iron and subjected to DBA's proprietary Thermal Stability Profiling (TSP) process, which heat-treats the rotor to relieve internal stress and maximize thermal stability under intense braking
• Kangaroo Paw Ventilation: Patented internal vane design featuring 144 diamond and teardrop-shaped pillars delivers up to 30% more surface area and 20% improved cooling efficiency compared to traditional straight-vane rotors
• CBN Machine-Turned Finish: Cubic Boron Nitride (CBN) machining ensures minimal disc thickness variation, reducing the potential for pad knock and premature wear
• Thermo-Graphic Heat Paint (TGHP): Color-coded paint markings on the rotor edge change color at specific temperature thresholds — green to white at 856°F, orange to yellow at 1022°F, and red to white at 1166°F — allowing easy monitoring of braking temperatures
• Anti-Rust Painted Non-Friction Areas: Hub and hat surfaces feature protective paint to resist corrosion and maintain a clean appearance
• Bi-Directional Design: Symmetrical slotting and drilling allows universal left/right installation
• Direct OEM Replacement: Designed as a direct-fit upgrade requiring no modifications

The DBA 4000 XS series is ideal for performance-oriented street use and spirited driving. Note: cross-drilled rotor configurations are not recommended for heavy track day or off-road applications. Sold individually.
