DBA DBA42366S 4000 Series T3 Slotted Performance Brake Rotor 340mm Front

The DBA DBA42366S 4000 Series T3 Slotted Brake Rotor is a direct replacement single-piece performance brake rotor engineered to deliver superior braking performance for high-performance street driving, track days, and motorsport applications. This 340mm front rotor features DBA's patented T3 bi-directional slot design with 48 precision CNC-machined tri-symmetrical curved slots that effectively evacuate brake pad friction dust and gases for consistently responsive braking.

Advanced Metallurgy and Construction:

• Cast from XG-150 high carbon alloyed iron for exceptional thermal capacity and durability
• Thermal Stability Profiling (TSP) heat treatment process minimizes warping and cracking under extreme conditions
• Patented Kangaroo Paw ventilation system with 144 diamond and teardrop-shaped pillars provides 30% more surface area and 20% better cooling efficiency compared to conventional straight vane designs
• CBN (Cubic Boron Nitride) machine-turned finish minimizes disc thickness variation and premature wear

Performance Features:

• T3 tri-symmetrical curved slots dampen vibration harmonics for quieter operation and smoother pedal feel
• Universal slot design eliminates the need for directional left/right specific rotors
• Thermographic heat paint markings change color at specific temperature thresholds to monitor peak braking temperatures and rotor fatigue
• Black high-temperature paint on non-friction areas prevents rust and enhances appearance
• Minimum thickness: 26mm

Ideal for performance enthusiasts demanding superior stopping power, enhanced heat dissipation, and extended service life. This rotor is recommended for street performance vehicles, track cars, and rally applications where consistent, fade-resistant braking is critical.
