DBA DBA4653XS 4000 Series Cross-Drilled and Slotted Brake Rotor

The DBA 4653XS is a premium cross-drilled and slotted performance brake rotor designed to work in conjunction with DBA's patented Kangaroo Paw ventilation system. The XS pattern increases the number of out-gassing exit points to allow brake pad friction gases to escape, increasing the consistency and effectiveness of every brake stop.

Advanced Materials and Heat Treatment:

• Constructed from DBA's proprietary XG-150 high carbon alloyed iron for superior strength and durability
• Features Thermal Stability Profiling (TSP), a proprietary heat treatment process that subjects the rotor to prolonged heat cycles under controlled conditions to relieve internal stresses and ensure maximum thermal stability
• Kangaroo Paw ventilation implements a series of 144 diamond and teardrop patterned pillars, achieving up to a 30% increase in surface area and 20% improvement in cooling efficiency compared to traditional straight vane designs
• Non-friction areas are painted gold for corrosion protection and enhanced appearance

Performance Features:

• Revolutionary universal drill and slot design eliminates the need for separate left and right slot designs
• Thermo-graphic paint markings on the edge change color at specific temperature thresholds—green changes to white at 856°F, orange to yellow at 1022°F, and red to white after 1166°F
• Increased surface area provides greater heat dissipation, minimizes brake fade, and prolongs service life for both pads and rotors
• Designed for high performance street use

The 4000 Series disc brake rotor is a direct replacement single piece brake rotor, designed for drivers seeking upgraded performance braking above and beyond standard OE levels. Sold individually.
