DBA DBA2812S Street Series T2 Slotted Disc Brake Rotor

The DBA DBA2812S is a Street Series T2 slotted disc brake rotor engineered as a direct OEM replacement with a meaningful performance upgrade. Sold as a single rotor, this unit features DBA's patented T2 slot design — a bi-symmetrical, CNC-machined slotting pattern that delivers improved braking response over standard solid rotors.

T2 Slot Technology:

• Patented bi-symmetrical T2 slots — CNC-machined for precision and consistency across the friction surface
• Curved slot geometry dampens vibration harmonics, reducing brake noise for a quieter, smoother pedal feel
• Increased number of exit points allow friction dust and gases to escape during braking, enhancing pad bite and reducing fade
• Universal left/right fitment — symmetrical design eliminates the need for separate handed rotors
• Promotes even pad wear and helps minimize pad surface glazing

Kangaroo Paw Vane Design:

• DBA's patented internal vane architecture features 144 diamond and teardrop-shaped pillars between the inner and outer rotor faces
• Delivers up to 20% better heat dissipation compared to conventional vane designs
• Increases dimensional stability and reduces the risk of rotor warpage under sustained braking loads

Premium Construction:

• Manufactured from high carbon content iron for reduced vibration and squealing
• CBN (Cubic Boron Nitride) machine-turned finish minimizes disc thickness variation and reduces the potential for pad knock and premature wear
• Centre-split core castings for increased heat transfer and thermal efficiency
• Black paint applied to all non-contact areas for corrosion resistance and clean appearance
• Rotor surface machined to micron-level smoothness for optimal pad bed-in and long pad life

The DBA2812S is backed by DBA's 12-month / 12,000-mile warranty from the original date of purchase. DBA (Disc Brakes Australia) brings over 30 years of brake engineering experience to every rotor they produce, supplying both the aftermarket and OE channels with proven, high-quality braking components.
