DBA DBA43058S 4000 Series T3 Slotted Front Brake Rotor

The DBA 4000 Series T3 is a direct replacement single-piece performance brake rotor designed for drivers seeking upgraded braking performance significantly beyond standard OE levels. This represents the ultimate in direct replacement performance brake rotors, featuring all the metallurgy advantages of the 4000 Series combined with DBA's patented T3 bi-directional slot design.

Advanced Materials and Construction:

• Cast from XG-150 high carbon alloyed iron and undergoing Thermal Stability Profiling (TSP) to handle increased stress and heat generated under intense braking applications
• Features patented Kangaroo Paw ventilation with 144 diamond and teardrop patterned pillars, achieving up to 30% increase in surface area and 20% improvement in cooling efficiency compared to traditional straight vane designs
• Manufactured from XG150 High Carbon Alloyed Iron with precision CNC machined slots

T3 Slot Technology:

• Tri-symmetrical slot design features precise CNC machined slots that deliver a quieter, more responsive, and smoother brake pedal feel
• Increased exit points allow brake pad friction dust and gases to escape, enhancing consistency and effectiveness of every brake stop
• Universal slot design eliminates the need for separate left and right rotors

Performance Monitoring Features:

• Equipped with Thermo-Graphic Heat Paint (TGHP) markings that change color when the rotor reaches predetermined critical temperature thresholds
• Black hub color with T3 Slot precision design
• Unidirectional design, 1-piece construction

Rated for severe motorsports use and recommended for all performance applications from street driving, track days, rally cars, and 4x4/SUV applications. This rotor is compatible with Subaru WRX VB (2022+) and Forester SK (2018+) front applications.
