DBA DBA42396S 4000 Series T3 Slotted Uni-Directional Brake Rotor

The DBA DBA42396S is part of DBA's 4000 Series T3 (T-Slot) line — the most advanced one-piece brake rotor in the DBA lineup. Engineered for both demanding street driving and track-day performance, the 4000 Series T3 rotor delivers consistent, fade-resistant braking through DBA's signature uni-directional slotting technology.

T3 Slotting Technology:

• DBA's patented T-Slot pattern channels heat and gases away from the pad surface, reducing brake fade under sustained high-temperature use
• Slots continuously sweep the brake pad face to remove debris and maintain a clean, even contact patch
• Uni-directional design ensures optimal slot geometry is maintained throughout the rotor's service life

Key Features:

• One-piece rotor construction for superior rigidity and thermal stability
• Designed for extreme road and race applications
• Improved bite and modulation compared to standard smooth rotors
• Helps reduce pad glazing and extends pad life
• Manufactured to meet or exceed OEM dimensional tolerances
• Sold individually (per rotor)

DBA (Disc Brakes Australia) is a globally recognized manufacturer of premium brake components. The 4000 Series T3 is the ideal upgrade for performance-oriented drivers seeking a rotor that handles the rigors of spirited driving, towing, or competitive motorsport without sacrificing daily drivability.
