DBA DBA4477S Series Slotted Brake Rotor - 4000 T3

The DBA DBA4477S is a 4000 Series T3 Slotted performance brake disc engineered by Disc Brakes Australia (DBA), one of the most trusted names in high-performance braking. Designed as a direct OEM replacement with a performance upgrade, this solid rotor delivers improved stopping power, reduced brake fade, and extended pad life compared to standard smooth rotors.

DBA's proprietary Geomet® corrosion-resistant coating protects the rotor hat and non-friction surfaces from rust and premature wear, helping maintain a clean, professional appearance over the life of the rotor. The T3 slot pattern — DBA's triple-slot design — continuously sweeps debris, gases, and heat away from the pad-rotor interface, keeping the braking surface clean and maximizing thermal performance.

Key Features:

• 4000 Series T3 Slotted Design: Triple-slot pattern evacuates heat, gas, and brake dust for consistent, fade-resistant braking
• Solid Rotor Construction: Matched to OEM specification for the correct application
• Geomet® Protective Coating: Corrosion-resistant finish on non-friction surfaces for long-term durability
• Direct OEM Replacement: Bolt-on fitment with no modifications required
• Performance Street Use: Ideal for spirited driving and demanding daily use
• DBA Quality Manufacturing: Engineered and tested to meet stringent Australian and international standards

The DBA4477S is a solid (non-vented) rotor, purpose-built for applications where the OEM specifies a solid disc. It pairs perfectly with DBA's range of performance brake pads for a complete braking upgrade. Whether you're looking to restore braking performance or step up to a higher level of feel and control, the DBA 4000 Series T3 delivers proven results on the street.
