Sharing all the benefits of the 4000 Series, 5000 Series rotors are a composite 2 piece direct replacement brake rotor. We use only the highest quality materials to ensure optimal performance under the most strenuous circumstances, combining high carbon cast iron rings with aerospace grade aluminium hats (T6061-T6) held together with National Aerospace Standards (NAS) bolts and crimp nuts.
5000 Series shares all of the performance technology featured in the 4000 Series, with the added benefits of further weight reduction and improved heat management via the aluminium hats.
The use of aerospace grade aluminium hats reduces the unsprung weight of the brake rotors, whilst allowing for uniform radial disc expansion throughout the cast iron rings and reduced heat transfer from disc to hub via the aluminium hats.
We offer both complete assemblies for first time replacement (hats and flat discs bolted together) along with replacement hats and flat disc rotors. This allows drivers to re use their DBA 5000 Series hats with DBA replacement flat discs (rings).
We recommend 5000 Series for high performance street vehicles, track day and club racing, rally applications and show vehicles.
 
XS provides all the benefits of 5000 Series, with a premium non-directional cross drilled and slotted design, plus a variety of finishes available on the rotor hub.
The introduction of our unique cross drilled and slotted design increases the number of exit points, allowing more brake pad friction dust and gases to escape through both the cross drilled holes and slots, resulting in better braking performance.
While providing a similar performance benefit to the T3 slot, the XS is a popular alternative for show cars.
XS rotors are denoted by the suffix (XS) in 5000 Series part numbers.
