DBA DBA540S Street Series T2 Slotted Brake Disc Rotor

The DBA DBA540S Street Series T2 Slotted Brake Rotor is a direct OE-replacement disc rotor engineered by Disc Brakes Australia (DBA) for drivers seeking a meaningful performance upgrade over a standard replacement rotor. Purpose-built for daily drivers, light commercial vehicles, and SUV applications — including demanding 4x4 use — this rotor pairs OEM-grade fitment with DBA's patented T2 slot technology for improved stopping power and longevity.

Patented T2 Slot Design:

• Precise CNC-machined bi-symmetrical curved slots deliver a quieter, more responsive brake pedal feel
• Increased exit points allow friction dust and gases to escape the pad-rotor interface, enhancing pad bite and reducing glazing
• Even slot distribution promotes consistent pad wear across the full friction surface, minimizing the formation of edge lips that cause squeal and vibration
• Symmetrical slot pattern allows universal left/right fitment

Kangaroo Paw Vane Ventilation System:

• DBA's patented internal vane design features 144 diamond and teardrop-shaped pillars between rotor faces
• Delivers up to 20% better heat dissipation compared to conventional vented rotor designs
• Faster rotor cooling reduces heat-induced fade and warpage, extending service life
• Centre-split core castings further improve heat transfer and thermal efficiency

Premium Construction:

• CBN (Cubic Boron Nitride) machine-turned friction surface finish minimizes disc thickness variation and reduces the potential for pad knock and premature wear
• Sized to exact OEM dimensions for a direct, bolt-on installation with no modification required
• Non-friction areas painted to inhibit rust and maintain appearance
• Backed by DBA's 12-month / 12,000-mile warranty against defects in materials and workmanship

With over 40 years of brake engineering experience, DBA delivers a rotor that goes beyond standard OEM replacement — offering superior thermal management, pad-friendly slot geometry, and robust construction suited to the rigors of both everyday driving and off-road 4x4 use.
