DBA DBA4947S 4000 Series T3 Slotted Performance Brake Rotor

The DBA 4000 Series T3 slotted brake rotor represents the ultimate in direct replacement single-piece performance braking technology. Engineered for drivers seeking upgraded performance above standard OE levels, this rotor combines advanced metallurgy with innovative design features for superior stopping power and durability.

Advanced Material Construction:

• Cast from XG-150 high carbon alloyed iron for exceptional strength and heat resistance
• Thermal Stability Profiling (TSP) heat treatment process eliminates internal stresses and maximizes thermal stability
• Handles extreme stress and heat from intense braking applications repeatedly
• Reduced metal fatigue and improved resistance to surface cracking

Patented T3 Slot Technology:

• Precise CNC-machined tri-symmetrical slot design for optimal performance
• Bi-directional universal design eliminates need for separate left and right rotors
• Multiple exit points facilitate rapid evacuation of brake pad friction dust and gases
• Delivers quieter operation with more responsive and smoother brake pedal feel
• Enhances pad bite and braking consistency for every stop

Kangaroo Paw Ventilation System:

• Patented design features 144 diamond and teardrop patterned pillars
• Up to 30% increase in cooling surface area compared to traditional straight vane designs
• 20% improvement in cooling efficiency for better heat dissipation
• Centre split core castings enhance heat transfer and thermal efficiency

Premium Manufacturing Features:

• CBN (Cubic Boron Nitride) machine-turned finish minimizes disc thickness variation
• Reduces potential for pad knock and premature wear
• Thermo-Graphic Heat Paint (TGHP) markings change color at critical temperature thresholds
• Allows monitoring of braking temperatures and rotor fatigue for informed maintenance decisions
• Black high-temperature coating on non-friction surfaces prevents rust and enhances appearance

This DBA 4000 Series T3 rotor is ideal for high-performance street driving, spirited canyon runs, and track day use. The combination of advanced materials, innovative slot design, and superior cooling makes it an excellent choice for enthusiasts demanding reliable, fade-resistant braking performance.
