DBA DBA42397S Series Slotted Brake Rotor - 4000 T3

The DBA DBA42397S is a high-performance T3 4000 Series slotted brake rotor engineered for extreme road and race applications. This advanced one-piece rotor features DBA's patented Thermal Stability Profiling (TSP) technology, which enhances thermal stability and reduces disc distortion under heavy braking conditions.

Key Features:

• T3 slot design provides efficient heat and gas dissipation while maintaining rotor strength
• Uni-directional slotting pattern optimized for consistent pad bite and reduced brake fade
• Thermal Stability Profiling (TSP) ensures even heat distribution across the rotor surface
• Kangaroo Paw ventilation pillars enhance cooling efficiency by up to 20%
• XG150 high-carbon iron alloy construction for superior crack resistance
• Precision CNC machining ensures perfect balance and minimal run-out
• Direct OEM replacement for easy installation

The 4000 Series T3 rotor is ideal for high-performance street vehicles, track day cars, and light racing applications where maximum braking performance and durability are essential. The slotted design continuously cleans the brake pad surface, removing debris and gases to maintain optimal friction. Each rotor is sold individually.
