Sharing all the benefits of the 4000 Series, 5000 Series rotors are a composite 2 piece direct replacement brake rotor. DBA 04-17 STi Front Drilled/Slotted 5000 Series 2 Pc Rotor w/Gold Hat 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.
 
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).
