DBA (Disc Brakes Australia) is a world-leading manufacturer of high-performance brake rotors and systems, engineered for street, off-road, and motorsport applications. Proudly designed and manufactured in Australia, DBA has been at the forefront of braking technology for over 40 years, combining advanced metallurgy, precision machining, and patented cooling innovations to deliver unmatched stopping power, heat dissipation, and durability. Trusted by performance enthusiasts, professional racers, and OEM manufacturers worldwide, DBA sets the industry benchmark for safety, reliability, and performance. Whether on the road or the track, DBA brakes provide the confidence to push limits while maintaining total control.

Sharing all the benefits of the 4000 Series, DBA's 5000 Series rotors are a composite 2 piece direct replacement brake rotor. DBA uses only the highest quality materials to ensure optimal performance under the most strenuous circumstances, combining high carbon cast-iron rings with aerospace grade aluminum hats (T6061-T6), held together with National Aerospace Standards (NAS) bolts and crimp nuts. The 5000 Series share all of the performance technology featured in the 4000 Series, with the added benefits of further weight reduction and improved heat management via aluminum hats. The use of aerospace grade aluminum hats reduces the unsprung weight of the brake rotors, while allowing for uniform radial disc expansion through the cast iron rings, and reduced heat transfer from disc to hub via the aluminum hats. DBA offers both complete assemblies for first time replacement (hats and flat discs bolted together) along with replacement hats and flat disc rotors (rings). This allows drivers to re-use their DBA 5000 Series hats with DBA replacement flat discs (rings). DBA recommends the 5000 Series for high performance street vehicles, track day and club racing and rally applications.
