DBA DBA42957S Series Slotted Brake Rotor - 4000 T3 279.5mm

The DBA DBA42957S is a high-performance slotted brake rotor from DBA's acclaimed 4000 Series T3 lineup, designed for drivers seeking upgraded braking performance beyond factory standards. This 279.5mm (11-inch) single-piece rotor combines cutting-edge materials with innovative design features to deliver exceptional stopping power for spirited street driving, track days, and towing applications.

Advanced Materials and Construction:

• Cast from XG-150 high-carbon alloyed iron for superior heat resistance and durability
• Thermal Stability Profiling (TSP) heat treatment process minimizes surface cracking and increases fatigue resistance under extreme braking conditions
• Thermo-Graphic paint markings allow for effective heat monitoring during performance driving
• Protective black coating on non-friction surfaces prevents rust and corrosion

Patented Performance Features:

• Kangaroo Paw ventilation design features 144 diamond and teardrop-patterned pillars for up to 30% increase in surface area and 20% improvement in cooling efficiency compared to traditional straight-vane designs
• T3 tri-symmetrical slotting with 48 precision CNC-machined curved slots provides bi-directional performance
• Slots continuously de-glaze brake pads for consistent performance and even wear
• Channels dissipate brake dust, gases, and water for improved pedal feel and all-weather performance
• Quieter operation with more responsive and smoother brake pedal feel compared to cross-drilled designs

Installation and Compatibility:

This rotor is a direct replacement for OEM rotors with no modifications required. Sold individually. Minimal bedding-in period required. Compatible with both OEM and aftermarket performance brake pads. Ideal when paired with high-performance brake pads for maximum braking system efficiency.
