DBA DBA2252S Street Series T2 Slotted Front Brake Rotor

The DBA DBA2252S Street Series T2 Slotted Brake Rotor is a premium front disc brake rotor engineered by Disc Brakes Australia (DBA) to deliver a meaningful upgrade over standard OEM rotors without stepping into full race-spec territory. It combines the proven reliability of the Street Series platform with DBA's patented T2 slot design for enhanced everyday performance and confident stopping power.

T2 Slot Technology

The defining feature of this rotor is DBA's patented T2 slotting pattern. Precise CNC-machined bi-symmetrical slots are engineered to reduce vibration harmonics and noise, delivering a quieter, more responsive, and smoother brake pedal feel. The increased number of exit points created by the T2 slots allows friction dust and gases to escape during braking, directly enhancing pad bite and consistency. The symmetrical slot design also promotes even pad wear and helps prevent glazing of pad surfaces.

Kangaroo Paw Vane Design

Integrated into the rotor's vented core is DBA's patented Kangaroo Paw ventilation system — a unique pattern of diamond and teardrop-shaped pillars that promotes superior airflow through the rotor. This design cools the rotor faster than conventional vane designs, increases dimensional stability under heat, and can boost thermal efficiency by up to 20% compared to standard rotor designs.

Precision Machining & Construction

• CBN (Cubic Boron Nitride) machine-turned friction surface finish minimizes disc thickness variation
• Centre-split core castings for increased heat transfer and thermal efficiency
• Symmetrical slotting for universal left/right fitment
• Rotor surface machined to micron-level tolerances for optimized pad bed-in and reduced premature wear

Key Features:

• DBA patented T2 bi-symmetrical CNC-machined slot design
• Patented Kangaroo Paw vane ventilation — up to 20% improved cooling efficiency
• Quieter, more responsive brake pedal feel vs. standard rotors
• Enhanced pad bite through improved gas and dust evacuation
• Promotes even pad wear and reduces surface glazing
• CBN-turned friction surface for precision fit and finish
• Direct OEM replacement — no modifications required
• Sold individually (single rotor)

The DBA Street Series T2 is the ideal choice for drivers seeking a genuine performance upgrade over stock brake components for daily driving and light performance use, backed by DBA's decades of braking engineering expertise.
