DBA DBA3023S Street Series T2 Slotted Disc Brake Rotor

The DBA DBA3023S Street Series T2 Slotted Brake Rotor is an entry-level enhanced performance disc brake rotor from Disc Brakes Australia (DBA), engineered to deliver better-than-OEM stopping power for street-driven vehicles. Sold as a single rotor, it is recommended to replace as a matched left-right pair for balanced braking performance.

The T2 features DBA's patented bi-symmetrical CNC-machined curved slots, which dampen vibration harmonics and reduce noise, resulting in a quieter, more responsive, and smoother brake pedal feel. The increased number of slot exit points allows friction dust and gases to escape during braking, continuously cleaning the pad contact surface and enhancing overall pad bite.

At the core of the rotor sits DBA's patented Kangaroo Paw ventilation system — 144 diamond and teardrop-shaped pillars between the inner and outer rotor faces that promote faster cooling, increased dimensional stability, and up to 20% greater thermal efficiency compared to conventional rotor designs. This advanced vane geometry resists heat-induced warpage and dramatically reduces brake fade.

The friction surface is Cubic Boron Nitride (CBN) machine-turned to micron-level precision, minimizing disc thickness variation (DTV) and the potential for pad knock. Non-friction areas are finished with black paint for both corrosion resistance and a clean, aggressive appearance.

Key Features:

• Patented T2 bi-symmetrical CNC-machined curved slot design for quieter, more responsive braking
• Patented Kangaroo Paw ventilation with 144 spaced pillars for superior heat dissipation
• Up to 20% greater cooling efficiency versus conventional rotor designs
• CBN (Cubic Boron Nitride) machine-turned friction surface for superior disc thickness consistency
• High carbon content iron construction reduces vibration and noise
• Black paint on all non-contact areas for corrosion resistance and appearance
• OEM-matched dimensions for direct bolt-on installation without modification
• Non-directional design — fits left or right position
• Sold individually; replacement as a left-right pair is recommended
• 12-month / 12,000-mile manufacturer warranty

The DBA Street Series T2 is the ideal upgrade for performance-conscious street drivers seeking improved heat management, fade resistance, and braking confidence over stock rotors, without the cracking risk associated with drilled designs.
