DBA Series Cross-Drilled Slotted Performance Brake Rotor

The DBA 4000 Series cross-drilled and slotted brake rotor (also called a drilled and slotted disc brake rotor or XS rotor) is a one-piece, direct-replacement performance rotor. Disc Brakes Australia (DBA) designed it for drivers who want stronger braking than standard OE rotors, plus a sporty look. It suits spirited street driving.

Key Features:

• High-carbon alloyed iron construction: The rotor is cast from high-carbon alloyed iron (XG-150). This helps reduce vibration and brake noise.
• Thermal Stability Profiling (TSP): This treatment relieves metal stress, so the rotor can handle repeated heavy heat cycles.
• Cross-drilled and slotted surface: More exit points let brake pad dust and gases escape. This helps keep braking consistent and improves pedal feel.
• Kangaroo Paw (KP) vane design: Where fitted, the ventilated vanes improve cooling efficiency and surface area compared with a traditional straight vane.
• Thermographic paint markings: Where fitted, the markings change color to show the rotor's operating temperature range.
• Corrosion protection: Non-friction areas are coated to help prevent rust.
• Bolt-on replacement: The one-piece design matches the shape and size of factory OEM parts.

Drilled rotor designs are not recommended for heavy off-road or track day use. For that kind of driving, DBA recommends its slotted-only T3 rotors. DBA recommends replacing rotors as a left and right pair for even braking performance.
