DBA DBA42565S Series Slotted Brake Rotor - 4000 T3

The DBA DBA42565S is a direct replacement single-piece performance brake rotor from DBA's acclaimed 4000 Series lineup, designed for drivers seeking enhanced braking performance beyond standard OE levels. This rotor is ideal for street driving, track days, autocross, and motorsport applications where superior heat management and consistent brake response are critical.

Advanced Materials and Construction:

• Cast from XG-150 high carbon alloyed iron for superior strength and durability
• Thermal Stability Profiling (TSP) heat treatment process relieves internal stresses and optimizes thermal stability
• Precision CNC machined tri-symmetrical T3 slot design for exceptional gas and dust evacuation
• Black high-temperature coating on non-friction areas prevents corrosion and enhances appearance

Patented Kangaroo Paw Ventilation:

• Features 144 diamond and teardrop patterned pillars in the rotor core
• Delivers up to 30% increase in surface area compared to traditional straight vane designs
• Provides 20% improvement in cooling efficiency for consistent performance under heavy braking

T3 Slotted Performance Design:

• Bi-directional tri-symmetrical curved slots increase exit points for friction gases and brake dust
• Dampens vibration harmonics for quieter operation and smoother pedal feel
• Non-directional design allows universal left/right installation
• Maintains cleaner rotor surface for more consistent brake friction

Thermo-Graphic Heat Paint Monitoring:

• Green, orange, and red heat-sensitive paint stripes change color at critical temperature thresholds
• Allows drivers to monitor peak rotor temperatures and optimize pad selection
• Helps match brake pad compounds to actual operating conditions
