DBA DBA2040S Street Series T2 Slotted Disc Brake Rotor 296mm

The DBA DBA2040S Street Series T2 Slotted Brake Rotor is a direct OE-replacement disc rotor engineered for drivers who want a meaningful performance upgrade over a standard replacement rotor without crossing into full competition territory. Built on DBA's proprietary XG-150 high-carbon cast iron alloy, this rotor delivers excellent thermal stability and natural resistance to heat-induced warping.

Patented T2 Slot Design:

• 32 CNC-machined bi-symmetrical curved slots allow brake dust and gases generated during braking to escape the friction surface efficiently
• Curved slot geometry reduces the noise and vibration harmonics associated with traditional straight-slotted rotors, delivering a quieter and smoother pedal feel
• Increased exit points enhance pad bite and help minimize pad glazing for consistent braking performance
• Bi-directional (universal) slot pattern means a single part number fits both left and right sides

Kangaroo Paw Ventilation System:

• DBA's patented internal vane design features 144 diamond and teardrop-shaped pillars for maximized passive cooling
• Increases cooling efficiency by up to 20% compared to conventional vented rotor designs
• Maintains dimensional strength and stability under heat cycles

Premium Manufacturing:

• Surface finished using CBN (Cubic Boron Nitride) machining to micron-level tolerances, minimizing disc thickness variation and reducing the potential for pad knock-back
• Centre-split core castings promote increased heat transfer and thermal efficiency
• Rotor diameter: 296mm

The DBA DBA2040S is sold as a pair and is ideal for daily drivers, light commercial vehicles, and SUV applications where reliable, fade-resistant braking performance is a priority. Pair with DBA Street Series or Street Performance brake pads for best results.
