We always have discussions with car enthusiasts who want to enhance their vehicle with top-notch brake rotors that can withstand the demands of high-performance driving. Many times, our conversations lead us to talk about the exceptional engineering from Disk Brakes Australia (DBA) in the land down under. Some of our favorite modification projects have involved using the DBA Drilled and Dimpled Street XD Coated Brake Rotors, both in the front and rear. This Australian manufacturer offers three remarkable brake rotor categories that cater perfectly to different markets, providing an excellent upgrade for those in our world seeking superior braking performance. The DBA Drilled and Dimpled Street XD Coated Brake Rotors are a quality product that looks great, exhibits exceptional performance, while also having the amazing technology behind the curtain to maintain their place on top.
One thing that many car enthusiasts may not be aware of is that all DBA Brake Rotors are direct replacements. This means that you don't need to make any special modifications to install them on your vehicle. The 4000 Series XD variant is particularly impressive, featuring DBA's unique non-directional cross-drilled and dimpled rotor design. Not only does this design provide superior cooling, but it also adds a sporty aesthetic to your vehicle. The smartly designed drilled and slotted product allows true function over form more than some of the most popular aftermarket products. This design allows gas trapped between the pad and the rotor to escape, resulting in solid, positive contact. DBA refers to this as Thermal Stability Profiling, which exceeds HD specifications.
The combination of dimples and drilled holes in DBA's engineering and design also provides enhanced rotor structural support compared to traditional cross-drilled techniques. The product specifications mention 144 diamond and teardrop patterned pillars, which increase the overall surface area by 30%. While the XD Coated Brake Rotor is perfect for high-performance driving on the street or track, it's not recommended for heavy off-road use. However, for those who stick to the pavement, there's no need to worry. With DBA's engineering expertise and the added aesthetic appeal, any vehicle equipped with these rotors will stand out from the crowd.
Disk Brakes Australia is renowned both locally and globally for their unmatched experience in manufacturing. We've already highlighted their impressive designs, intelligent engineering, and proven performance. However, it's important to acknowledge the reputation and heritage that this company has earned through their unwavering support for motorsport enthusiasts. These enthusiasts, who are ultimately individuals within tight, informed car owner communities, find home when expressing themselves through their cherished modifications and builds. Being owned and supported by a major conglomerate allows DBA to push, innovate, and improve their products as of one of Australia’s leading automotive aftermarket product brands. In addition to their continuous efforts in rotor engineering, DBA also excels in designing, engineering, and manufacturing Brake Pads and shoes, calipers, brake fluids, sensors, and much more. This extensive range of offerings clearly demonstrates their commitment to those who live for high-performance vehicles and the upgrades that fuel their passion.
The 4000 Series disc brake rotors from DBA serve as a direct replacement single-piece brake rotor, offering drivers an upgrade in performance braking beyond standard OE levels. Crafted from high carbon alloyed iron and subjected to Thermal Stability Profiling, DBA's metallurgy ensures the rotor's ability to handle the elevated stress and heat generated during intense braking applications consistently. The innovative Kangaroo Paw ventilation system, comprising 144 diamond and teardrop patterned pillars, increases surface area by up to 30% and enhances cooling efficiency by 20%, surpassing traditional straight vane designs. This makes the 4000 Series an ideal choice for drivers seeking improved braking performance and durability.
DBA's mid-series enhanced performance rotor incorporates Thermal Stability Profiling, enhancing its ability to handle heat effectively. The inclusion of Thermo-Graphic paint markings on the rotor enables precise heat monitoring, with color changes indicating the temperature reached. This feature allows users to accurately match the appropriate brake pad compound, making it an excellent choice for street use. The blank design of the rotor ensures outstanding performance, surpassing the longevity of other drilled or slotted models

- XH150 High carbon alloyed iron materials
- Thermographic Temperature Monitoring system
- Paint protection on non-friction areas
The T3 Slot rotors boast 48 precision CNC machined slots, featuring tri-symmetrical curve slots that serve as efficient out-gassing exit points for brake pad friction gasses, promoting enhanced responsiveness. With an increased surface area, these slots contribute to greater heat dissipation for improved performance. The Kangaroo Paw design incorporates 144 diamond and teardrop pillars, creating a ventilation system that enhances heat dissipation and aids in maintaining optimal braking temperatures. Crafted from XH150 high carbon alloyed iron materials, these rotors exhibit durability and resilience. The addition of a thermographic temperature monitoring system allows for real-time temperature assessment, while paint protection on non-friction areas ensures resistance against corrosion, contributing to the overall longevity and reliability of the rotors.

The surface design of these rotors features symmetrical slots and/or chamfered drill holes, promoting the efficient exit of friction dust and gasses to provide a quieter and more responsive pedal feel. With anti-rust measures such as painted non-friction areas or full En-shield coating, these rotors not only prevent rust but also enhance their appearance. The bi-directional use is facilitated by symmetrical slotting and/or drilling for universal left/right application. Employing thermal stability profiling through heat treatment cycles, the microstructure of the iron is realigned, resulting in increased rotor stability and durability. The centre-split core castings contribute to enhanced heat transfer and thermal efficiency, while thermographic heat paint assists in monitoring braking temperatures and rotor fatigue. The CBN machine-turned finish minimizes disc thickness variation, reducing the potential for pad "knock" and premature wear. Crafted from a high carbon alloyed iron formulation that optimally interacts with DBA's thermal stability profiling, these rotors increase the capacity to handle constant and extreme heat over prolonged periods. The unique Kangaroo Paw vane design further contributes to up to 20% better heat dissipation, ultimately enhancing braking effectiveness and prolonging brake life.
