DBA DBA42863S 4000 Series T3 Slotted Brake Rotor

The DBA 4000 Series T3 Slotted Brake Rotor is a direct replacement single-piece performance rotor designed for drivers seeking enhanced braking performance beyond standard OE levels. Cast from high carbon alloyed iron and featuring DBA's proprietary Thermal Stability Profiling (TSP), this rotor delivers exceptional heat handling and durability for street driving, spirited weekend runs, and track day applications.

Advanced T3 Tri-Symmetrical Slot Design:

• Features 48 precision CNC-machined tri-symmetrical slots that increase exit points for brake pad friction dust and gases
• Provides quieter operation, more responsive pedal feel, and smoother braking compared to traditional designs
• Bi-directional universal design eliminates the need for separate left and right rotors
• Continuously de-glazes brake pads for improved efficiency and consistent performance

Patented Kangaroo Paw Ventilation:

• Incorporates 144 diamond and teardrop-shaped pillars in the rotor core
• Delivers up to 30% increase in surface area for superior heat dissipation
• Achieves 20% improvement in cooling efficiency compared to conventional straight vane designs
• Enhances dimensional stability and reduces brake fade during aggressive braking

Thermal Stability Profiling & Monitoring:

• TSP heat treatment process realigns the iron microstructure for increased rotor stability and fatigue resistance
• Thermo-Graphic paint markings change color at specific temperature thresholds to visually monitor rotor heat
• Helps identify optimal brake pad compound selection based on actual operating temperatures
• Extends service life for both rotors and brake pads

Premium Construction Features:

• Centre-split core castings maximize heat transfer and thermal efficiency
• Painted non-friction areas prevent rust and enhance appearance
• Cubic Boron Nitride (CBN) machine-turned finish minimizes disc thickness variation
• Direct bolt-on installation with no mechanical modifications required

Each rotor is sold individually. The DBA 4000 Series T3 represents the ideal balance of performance, durability, and value for enthusiasts who demand professional-grade braking performance for both street and track use.
