DBA DBA47420XS 4000 Series XS Drilled and Slotted Performance Brake Rotor

The DBA 4000 Series XS rotor combines advanced technology and premium materials to deliver maximum performance braking beyond standard OE levels. Manufactured from high carbon, heat-treated XG-150 iron alloy and featuring the patented Kangaroo Paw ventilation system with a unique cross-drilled and slotted design, this direct replacement rotor is engineered for drivers seeking superior stopping power and thermal management.

Advanced Cooling Technology:

• Patented Kangaroo Paw ventilation with 144 diamond and teardrop patterned pillars provides up to 30% increase in surface area and 20% improvement in cooling efficiency compared to traditional straight vane designs
• Cross-drilled and slotted design increases exit points for brake pad friction dust and gases, resulting in better braking performance
• Thermal Stability Profiling (TSP) process subjects the XG-150 grey iron to prolonged heat cycles under controlled conditions to relieve internal stresses and ensure maximum thermal stability

Premium Features:

• Gold finish on the rotor hub for enhanced appearance and corrosion protection
• Thermo-Graphic heat paint markings change color at specific temperatures for easy monitoring of rotor heat
• Symmetrical slots and chamfered drill holes facilitate the exit of friction dust and gases for quieter, more responsive pedal feel
• Symmetrical slotting and drilling for universal left/right use
• Painted non-friction areas prevent rust and enhance appearance

The XS version is ideal for high-performance street use, offering exceptional heat dissipation and consistent braking performance. Each rotor is sold individually and designed for direct bolt-on installation with stock calipers.
