DBA
DBA, Disc Brakes Australia, was founded in Sydney in 1976. Its range here is mostly brake discs, with pads to match and a few Street Series calipers.
The discs are grouped by series and slot pattern. Street Series T2 and 4000 Series T3 discs make up most of the range, and 5000 Series two-piece discs are listed along with their replacement rings. Most DBA discs here have a bi-slotted face, some also cross-drilled and a few plain. Many use the Kangaroo Paw internal vane design, and a large share are listed as ECE R90 approved. The pads step up from Street Series (an OE-type ceramic) and Street Performance to Xtreme Performance (a semi-metallic carbon fibre sport pad) and Racing Performance.
Toyota has the most listings, followed by Audi, Volkswagen, Subaru, Nissan, Ford, BMW and Lexus. The Subaru Impreza, Audi TT and A3, Volkswagen Golf and Seat Leon feature most often.
Next to the other disc ranges here, DBA is the one built around slot patterns and internal vane design rather than plain, drilled or dimpled faces.

Description
The DBA 4000 Series T3 bi-directional slotted disc brake rotors are single-piece brake rotors that are meticulously designed and engineered to deliver a high performance braking experience that is significantly quieter, more responsive, and offers a smoother pedal feel. Formulated with High Carbon Alloyed Iron, these rotors excel in interacting with DBA’s thermal stability profiling (TSP), enhancing the rotor’s ability to withstand consistent and extreme heat during prolonged periods.
