DBA DBA2174S Street Series T2 Slotted Disc Brake Rotor

The DBA DBA2174S Street Series T2 Slotted Brake Rotor is a direct OE-replacement upgrade rotor engineered for drivers who want a meaningful step up from standard rotors without crossing into full race-level hardware. Built by Disc Brakes Australia (DBA) — a recognized leader in brake rotor quality, safety, and performance with over 30 years of engineering experience — this rotor delivers confident, consistent stopping power for everyday street driving.

At the heart of the T2 design is DBA's patented CNC-machined bi-symmetrical slot pattern. These precisely machined curved slots serve a dual purpose: they dampen vibration harmonics to reduce noise and deliver a quieter, smoother, more responsive brake pedal feel, while also multiplying the number of exit points available for friction dust and gases generated during braking. Clearing that debris more effectively keeps pad surfaces cleaner, minimizes glazing, promotes even pad wear, and allows the pad to maintain a firmer, more consistent bite throughout the life of the rotor.

Key Features:

• Patented T2 Bi-Symmetrical Slot Design — CNC-machined curved slots for improved pad bite, reduced glazing, and quieter operation
• Kangaroo Paw Vane Technology — DBA's unique 144-pillar diamond and teardrop vane pattern increases cooling efficiency by up to 20% over conventional rotor designs, boosting dimensional stability and prolonging brake life
• Centre-Split Core Casting — Improves heat transfer and thermal efficiency under repeated braking
• CBN (Cubic Boron Nitride) Machine-Turned Friction Surface — Minimizes disc thickness variation to reduce the potential for pad knock and premature wear
• Universal Left/Right Fitment — Symmetrical slot design eliminates the need for separate left- and right-hand part numbers
• Direct OE Replacement — Bolt-on fitment with no modifications required
• Street Series Performance Level — Ideal OE-level upgrade; a step above plain rotors, positioned below DBA's T3 and 4000/5000 Series for high-performance or track use

The DBA DBA2174S is sold as a single rotor. DBA Street Series rotors are benchmarked for use with DBA Street Series or DBA Street Performance brake pads for optimum performance and wear compatibility.
