DBA DBA2456S Street Series T2 Slotted Disc Brake Rotor 300mm

The DBA DBA2456S Street Series T2 Slotted Brake Rotor is a high-performance, direct-replacement disc rotor engineered for everyday driving with the added safety and stopping power of DBA's patented T2 slot design. Measuring 300mm in diameter, this rotor is sold individually — order two for a complete axle set.

DBA's T2 slot technology features precision CNC-machined bi-symmetrical curved slots that dampen vibration harmonics, reduce noise, and deliver a quieter, more responsive, and smoother brake pedal feel. The universal slot design eliminates the need for separate left and right rotors, simplifying fitment and inventory.

The friction surface is finished using CBN (Cubic Boron Nitride) machine turning, which minimizes disc thickness variation (DTV) and improves parallelism — resulting in a more dimensionally precise and stable surface compared to conventionally ground rotors. DBA's patented Kangaroo Paw vane design provides up to 20% better heat dissipation over conventional rotor designs, increasing braking effectiveness and prolonging the service life of both pads and rotors.

Key Features:

• Patented T2 bi-symmetrical CNC-machined curved slots reduce vibration and noise
• Universal slot design — fits both left and right positions (no handed fitment)
• Increased out-gassing exit points allow friction dust and gases to escape, enhancing pad bite
• CBN machine-turned friction surface for improved DTV and parallelism
• Patented Kangaroo Paw vane design — up to 20% better heat dissipation vs. conventional rotors
• Centre-split core castings for increased heat transfer and thermal efficiency
• Minimizes brake fade and improves braking consistency
• Prolongs service life for both brake pads and rotors
• Ideal for daily commuting, towing, heavy-duty, and spirited street use
• 300mm rotor diameter | 28mm thickness | 47.3mm hat height

Manufactured by Disc Brakes Australia (DBA), an Australian-owned company with over three decades of brake engineering expertise and multiple AAAA Gold Manufacturer Award wins. The DBA2456S is a trusted upgrade over standard OE rotors for drivers seeking improved performance without moving to a full race-oriented setup.
