DBA DBA2856S Street Series T2 Slotted Brake Disc Rotor

The DBA DBA2856S Street Series T2 Slotted Brake Rotor delivers a proven performance upgrade over standard OE replacement rotors, combining everyday drivability with the added safety and responsiveness of DBA's patented T2 slot technology. Sold individually — order two for a complete axle set.

DBA (Disc Brakes Australia) is an Australian-owned manufacturer with over three decades of engineering expertise, recognized as Australia's most highly awarded automotive aftermarket parts manufacturer. Every Street Series rotor is built to precise tolerances and designed as a direct OE replacement with enhanced performance characteristics.

T2 Slot Technology:

• Bi-symmetrical CNC-machined curved slots dampen vibration harmonics and reduce brake noise for a quieter, smoother pedal feel
• Increased out-gassing exit points allow friction dust and gases to escape, enhancing pad bite and braking consistency
• Universal slot design eliminates the need for separate left and right rotors
• Minimizes pad glazing and promotes even pad wear, extending service life for both pads and rotors

Kangaroo Paw Vane Design:

• Patented internal vane geometry with 144 diamond and teardrop-shaped pillars for optimized airflow
• Cools the rotor faster and improves dimensional stability under heat
• Boosts thermal efficiency by up to 20% compared to conventional rotor designs
• Centre-split core castings further increase heat transfer for reduced brake fade

Precision Surface Finish:

• CBN (Cubic Boron Nitride) machine-turned friction surface delivers superior disc thickness variation (DTV) control and parallelism
• Provides a more dimensionally precise and stable finish compared to standard ground rotors
• Micron-level surface accuracy promotes healthier pad bed-in and reduces premature pad wear

The DBA2856S is ideal for daily driving, spirited street use, towing, and heavy-duty applications where reliable, fade-resistant braking performance is essential.
