DBA DBA42622S 4000 Series T3 Slotted Front Brake Rotor

The DBA DBA42622S is a high-performance front brake rotor from the 4000 Series T3 line, designed for drivers seeking upgraded performance braking well beyond standard OE levels. Cast from XG-150 high carbon alloyed iron and undergoing DBA's proprietary Thermal Stability Profiling (TSP) process, this rotor is engineered to handle the increased stress and heat generated during intense braking applications.

Key Features:

• Patented T3 bi-directional slot design with tri-symmetrical CNC machined slots for quieter operation and more responsive pedal feel
• Kangaroo Paw ventilation pattern with 144 diamond and teardrop pillars for up to 30% increased surface area and 20% improved cooling efficiency
• Thermal Stability Profiling (TSP) heat treatment process for maximum thermal stability and reduced metal fatigue
• CBN (Cubic Boron Nitride) machine turned finish minimizes disc thickness variation and premature wear
• Temperature-indicating paint markings change color at specific thresholds to monitor braking temperatures
• Black high-temperature coating on non-friction areas prevents rust and enhances appearance
• Single-piece direct replacement design for easy installation

The T3 slot design increases exit points for brake pad friction dust and gases, improving consistency and effectiveness with every brake stop. Rated for severe motorsports use and heavy-duty applications, this rotor delivers exceptional durability—lasting up to three times longer than standard rotors on the market.
