DBA DBA42847S 4000 Series T3 Slotted Rear Brake Rotor

The DBA 42847S is a high-performance rear disc brake rotor from DBA's acclaimed 4000 Series, designed for drivers seeking upgraded braking performance beyond standard OE levels. This single-piece direct replacement rotor features DBA's advanced T3 tri-symmetrical slot design for enhanced braking consistency and pedal feel.

Advanced T3 Slotting Technology:

Built on the foundations of DBA's T2 slot design, the T3 configuration features additional precise CNC-machined tri-symmetrical slots that create more exit points for brake pad friction dust and gases. This results in a quieter, more responsive, and smoother brake pedal feel while increasing the consistency and effectiveness of every brake stop. The universal slot design eliminates the need for separate left and right rotors.

Premium Materials and Construction:

• Cast from XG-150 high carbon alloyed iron for superior heat handling capability
• Thermal Stability Profiling (TSP) heat treatment realigns the microstructure for increased rotor stability and durability
• Kangaroo Paw ventilation design with 144 diamond and teardrop-patterned pillars provides up to 20% improvement in cooling efficiency
• CBN (Cubic Boron Nitride) machine-turned finish minimizes disc thickness variation
• Thermo-Graphic Heat Paint (THGP) markings change color at specific temperature thresholds to monitor braking temperatures

Performance Applications:

The 4000 Series T3 rotors are recommended for all high-performance applications including street driving, track days, rally cars, SUVs, light utility vehicles, and even armored vehicles. The advanced metallurgy handles the increased stress and heat generated under intense braking applications time and time again.

Each rotor is a direct replacement for OE applications and comes in moisture-proof corrosion protection packaging. Non-friction areas are painted to prevent rust and enhance appearance.
