DBA DBA42500S 4000 Series T3 Slotted Brake Rotor

The DBA 42500S is a high-performance single-piece brake rotor from the 4000 Series T3 line, engineered for drivers demanding superior braking performance beyond standard OE levels. Cast from XG-150 high carbon alloyed iron and undergoing Thermal Stability Profiling (TSP), this rotor handles increased stress and heat generated under intense braking applications, making it ideal for both spirited street driving and weekend track use.

Key Features:

• Tri-symmetrical slotted design specifically engineered to reduce vibration and noise while increasing out-gassing exit points for better brake pad performance
• Patented Kangaroo Paw ventilation with 144 diamond and teardrop patterned pillars achieves up to 30% increase in surface area and 20% improvement in cooling efficiency compared to traditional straight vane designs
• Thermal Stability Profiling (TSP) process subjects XG-150 grey iron to prolonged heat cycles under controlled conditions to relieve internal stresses, ensuring maximum thermal stability and reduced metal fatigue
• Thermo-Graphic Heat Paint (TGHP) stripes of Green, Orange and Red change color once rotor reaches predetermined critical temperature thresholds, allowing drivers to monitor peak braking temperatures
• Universal slot design eliminates left and right discs for simplified installation
• Black high-temperature coating on non-friction areas prevents corrosion and enhances appearance

Rated for severe motorsports use, these rotors handle the heat and high friction characteristics of even the most aggressive race pads. On average, these rotors last 3x longer than most other rotors on the market. Front position rotor sold individually.
