5000 Series rotors are a composite 2 piece direct replacement brake rotor - sharing all the benefits of the 4000 Series. 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.
