DBA DBA421X Street Series Gold Cross-Drilled and Slotted Vented Front Disc Brake Rotor

The DBA DBA421X Street Series Gold is a cross-drilled and slotted vented front disc brake rotor engineered by Disc Brakes Australia (DBA) for daily drivers seeking a meaningful upgrade over standard OEM rotors. Manufactured to exceed OEM standards, this rotor delivers improved braking response, better heat management, and enhanced durability straight out of the box with no modifications required.

The Street Series Gold X features a distinctive cross-drill and slot pattern that increases the number of outgassing exit points, allowing friction gases and heat to escape more efficiently during braking. This results in more consistent, fade-resistant stopping power. The non-directional design eliminates the need for separate left- and right-hand rotors, simplifying installation and parts management.

Key Features:

• Cross-Drilled and Slotted Design: Maximizes outgassing and cooling for more consistent and effective braking performance
• Kangaroo Paw Ventilation: DBA's patented 144 diamond and teardrop pillar vane design delivers up to 20% better heat dissipation compared to conventional rotors
• Gold High-Temperature Coating: Applied to non-friction surfaces for superior corrosion resistance and a premium appearance behind open-style alloy wheels
• CBN Machine-Turned Finish: Cubic Boron Nitride machining minimizes disc thickness variation, reducing the potential for pad knock and premature wear
• Non-Directional Drill Pattern: Eliminates the need for dedicated left and right rotors for easier fitment
• Minimizes Brake Fade: Increased surface area and ventilation prolong service life for both pads and rotors
• OEM-Level Direct Replacement: Installs without modifications; ideal for daily drivers and light commercial or SUV use
• Manufactured to Industry-Leading Standards: DBA is certified to ISO 9001, QS 9000, TS 16949, and TUV standards

The DBA Street Series Gold cross-drilled and slotted rotor is sold individually — order two for a complete axle set. It combines purposeful performance engineering with a premium finish, making it an excellent choice for drivers who want both improved braking capability and a distinctive look.
