DBA
DBA, Disc Brakes Australia, was founded in Melbourne 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
DBA4545S – 4000 Series T3 Brake Rotor; Front The 4000 Series T3 stands as the pinnacle in direct replacement single-piece performance brake rotors, encompassing all the metallurgy advantages of the 4000 Series with the addition of DBA’s renowned T3 bi-directional slot design. Evolved from the T2 slot foundation, the T3 slot design introduces precise CNC machined tri-symmetrical slots, resulting in a notably quieter, more responsive, and smoother brake pedal feel. The T3 slot enhances the braking experience by increasing the number of exit points for brake pad friction dust and gases, ensuring a consistent and effective performance with every brake stop. The majority of DBA’s 4000 Series Brake Rotors showcase the innovative Kangaroo Paw ventilation system. This system integrates a pattern of 144 diamond and teardrop-shaped pillars, delivering an outstanding 30% increase in surface area and a remarkable 20% enhancement in cooling efficiency when compared to conventional straight vane designs. Additionally, all 4000 Series Brake Rotors are equipped with Thermographic heat paint markings. These markings undergo colour changes at specific temperature thresholds, providing a valuable visual aid for monitoring braking temperatures and rotor fatigue. Ideal for high-performance applications, we highly recommend the 4000 Series T3 brake rotors for drivers seeking the utmost in braking excellence. Elevate your driving experience with the superior performance and innovation of the DBA 4000 Series T3 brake rotors.
