DBA 43701S 4000 Series T3 Slotted Brake Rotor

The DBA 43701S is a high-performance replacement brake rotor from DBA's 4000 Series T3 line, engineered for drivers seeking upgraded braking performance beyond standard OE levels. This single-piece performance rotor features DBA's patented T3 bi-directional slot design, delivering exceptional stopping power for street driving, track days, and demanding performance applications.

Advanced T3 Slotting Technology:

Built on the foundation of DBA's proven T2 slot design, the T3 features additional precision CNC-machined tri-symmetrical slots that provide a quieter, more responsive, and smoother brake pedal feel. The symmetrical slotting allows for universal left/right fitment and creates multiple exit points for brake pad friction dust and gases to escape, ensuring consistent and effective braking performance with every stop.

Premium Construction and Materials:

• Cast from XG-150 high carbon alloyed iron for superior strength and heat resistance
• Thermal Stability Profiling (TSP) heat treatment process relieves internal stresses and optimizes the rotor material for extreme braking conditions
• 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
• Center split core castings enhance heat transfer and thermal efficiency
• CBN (Cubic Boron Nitride) machine-turned finish minimizes disc thickness variation and reduces pad knock

Performance Features:

• Thermo-Graphic Heat Paint (TGHP) markings change color at critical temperature thresholds to help monitor rotor temperatures and optimize pad selection
• Improved fatigue resistance minimizes surface cracking during prolonged heavy braking
• Black high-temperature coating on non-friction surfaces prevents rust and enhances appearance
• Designed for severe motorsports use, rally cars, performance street vehicles, and demanding 4x4/SUV applications

DBA's 4000 Series T3 rotors are engineered to handle the increased stress and heat generated under intense braking applications, delivering reliable performance time and time again.
