Disc Brakes Australia - better known by their initials, DBA - are a highly-respected designer and manufacturer of top-quality high-performance disc brake rotors. Over four decades, their commitment to innovation and quality backed by intensive research and development has firmly entrenched DBA as a global player in the technology-driven world of superior disc brake rotor solutions. No matter what you drive - be it a daily-driver, 4WD, commercial vehicle, weekend toy or a track-only weapon - DBA's range of disc brake rotors can truly enhance the stopping power of your car.
Why Buy DBA
Brakes are one of the most important parts on your car ensuring they work when you need them the most is can be a life or death matter with DBA rotors you can rest assured you have a quality product when you need it the most. Manufactured to the highest standards with high grade materials you can count on DBA brake disc when you need it the most.
From the beginning of a disc brake rotor's manufacturing process at the foundry, right through to the final machining regimen, DBA have invested heavily in the know-how and infrastructure to create world-leading products. Their own proprietary cast iron formulation - known as XG-150 - is a carbon-rich creation that, when combined with another of their techniques, Thermal Stability Profiling (TSP), results in extremely strong disc brake rotor castings which possess excellent thermal conductivity properties, just what you want in a disc brake rotor! The final step in production is another area where DBA excel via their use of Cubic Boron Nitriding (CBN), a refining process which leaves the disc brake rotor with a surface finish that is far superior to a conventionally-ground surface found on other rotors.
DBA are perhaps best known for their "Kangaroo Paw" ventilation system. Instead of a series of straight vanes centrally located within each rotor casting, DBA's patented method of using 144 Kangaroo Paw-shaped pillars as the central component of each rotor casting better ensures rotor temperatures stay within optimum range by more efficiently channeling air through the rotor core than straight vanes can. Not only do they enable better ventilation, the Kangaroo Paw pillars also give better support to the friction surfaces of the rotor enabling better performance, strength and stability whilst also providing more thermal mass than a rotor with straight vanes, boosting efficiency and performance even further.
Slots and Cross-Drilling
Although the practice of machining slots into the face of disc brake rotors has been used for years to enable the out-gassing created between brake pad and rotor friction surface places to escape, DBA have taken things further by creating their own slot profiles. 'T2' disc brake rotors feature 32 CNC-machined bi-symetrical curved slots into the face of each rotor, designed to not only improve brake pad out-gassing but also reduce vibration often found in rotors with straight slot designs. The T2 slots are also universal in nature meaning you don't have to purchase "handed" left-and-right-specific rotors any more. Unique to both the Club Spec 4000 and all 5000 Series disc brake rotors, the 'T3' slot design feature an additional 16 slots per rotor over the 'T2' rotors for even better response, pedal feel and efficiency. 'X Gold' disc brake rotors, meanwhile, feature DBA's XS non-directional slot layout combined with a particular cross-drilled pattern that, like the slots, aid in brake cooling and overall performance. Plus they look good, too!
Stage 1 - Daily Driver - OE Direct Replacement
DBA's range of Original Equipment (OE) Direct Replacement disc brake rotors have been designed to not only meet but indeed surpass the requirements of vehicle manufacturers across the globe and are perfect for use in all types vehicles which experience normal, everyday conditions the average motorist might encounter. Additional reasons for choosing DBA OE Direct Replacement disc brake rotors include the aforementioned CBN surface finish treatment which means a better interface between rotor and brake pad than you'll get with other rotors. Certain models of DBA OE DIrect Replacement disc brake rotors come with Kangaroo Paw ventilation and/or DBA's new 'En-Shield' treatment, a baked-on protective coating that keeps the entire rotor free from corrosion without contaminating the brake pad surfaces!
Stage 2 - Uprated Performance - T2
A set of DBA T2 disc brake rotors are the ideal choice when you want to start improving overall stopping power - in conjunction with some nicer brake pads, for example - of your vehicle. Equipped with DBA's 'T2' 32 CNC-machined curved bi-symmetrical slots for efficient brake pad out-gassing and overall cooling and efficiency, certain models of 'T2' rotors also feature DBA's ingenious Kangaroo Paw ventilation system. All 'T2' disc brake rotors come with paint protection on non-friction areas, keeping those areas of the rotors free from corrosion and looking good.
Stage 3 - Performance AND Looks - X Gold
DBA's X Gold disc brake rotors can be used interchangeably with equivalent T2 rotors, they're just more suited to looking good and giving that "big brake" look thanks to the use of gold paint on non-friction surfaces. Instead of the 'T2' slots, the X Gold disc brake rotors feature their own specific XS non-directional slotted and cross-drilled cooling pattern.
Stage 4 - High-Performance Street - 4000 Series HD Direct Replacement
Here is where things start to get serious - DBA's 4000 Series HD Direct Replacement disc brake rotors are just the ticket for high-performance braking. Making use of DBA's own XG-150 high-carbon castings and Thermal Stability Profiling, 4000 Series HD Direct Replacement disc brake rotors enable constant extreme heat cycles designed specifically to cope with regular hard application of the brake pedal! To let you know how your rotors are coping under adverse conditions, the 4000 Series HD Direct Replacement disc brake rotors also feature Thermographic Temperature Monitoring, a trio of temperature-sensitive paint markings designed to change colour at certain temperature points.
Stage 5 - High-Performance Street and Show - 4000 Series XS
Just like the X Gold rotors are much the same as their equivalent T2 rotors with a few select differences in appearance, the 4000 Series XS disc brake rotors by DBA build on the 4000 Series HD Direct Replacement rotors but come with gold-painted non-friction surfaces and a unique non-directional XS cross-drill and slot design.
Stage 6 - Weekend Warrior - 4000 Series Club Spec Road and Race
If your car sees regular race track action, yet still gets driven on the street from time to time, then the 4000 Series Club Spec Road and Race disc brake rotors by DBA are for you. Perhaps the biggest difference between the 4000 Series Club Spec rotors and others are the use of DBA's 'T3' slot profiling and a central aluminium hat structure. Along with 48 of the 'T3' design CNC-machined tri-symetrical curved slots in addition to all of DBA's other innovations - such as the CBN surface finishing, use of Kangaroo Paw ventilation, XG-150 material with TSP material treatment, Thermographic Temperature Monitoring paint markings and paint protection on non-friction surfaces - it is the Aluminium central hat that is perhaps the biggest difference. By equipping the 4000 Series Club Spec disc brake rotors with an Alumalite 6061-T6 heat-treated central hat, it massively improves rotor performance by allowing even disc expansion and lower transfer of heat from the central hat to the car's wheel hub - no more rotor cracking as they cool from high temperatures! The use of an aluminium central hat also reduces unsprung weight boosting performance again.
Stage 7 - Race - 5000 Series 2-piece
The 5000 Series Club Spec Road and Race disc brake rotor by DBA build on the 4000 Series Club Spec Road and Race items by taking the central aluminium hat design and converting it to a 2-piece rotor design with a separate hat - it's a bit more race-oriented and also enables replacement of just the outer rotor assembly instead of the hat and rotor as in the 4000 Series Club Spec units.
