DBA DBA42363S 4000 Series T3 Slotted Brake Rotor

The DBA DBA42363S is a 4000 Series T3 Slotted brake rotor from Disc Brakes Australia (DBA), engineered for performance street and light track use. DBA's 4000 Series rotors are manufactured to meet or exceed OEM standards while delivering improved braking performance through their signature slotting technology.

The T3 slot pattern features DBA's patented triple-slot configuration, designed to continuously clean and deglaze brake pad surfaces, improve bite, and efficiently evacuate heat, gas, and debris from the rotor face. This results in more consistent braking feel, reduced brake fade, and extended pad life compared to standard smooth rotors.

Key Features:

• T3 Slotted Pattern – DBA's patented triple-slot geometry for optimized pad contact and heat dissipation
• 4000 Series Construction – Premium quality cast iron for excellent thermal stability and durability
• Kangaroo Paw (KP) Venting – Directional curved vanes improve internal airflow for superior cooling
• Electrophoretic Coating – Corrosion-resistant finish on non-friction surfaces to extend rotor life
• Balanced and Fine-Finished – Precision machined for minimal runout and vibration-free braking
• Street and Track Capable – Suitable for performance driving on road and occasional track days

The DBA42363S is a direct-fit replacement rotor designed for precise, no-modification installation. DBA rotors are manufactured in Australia and are a trusted upgrade in the performance and enthusiast market worldwide.
