DBA - 5000 Series Front Rotor Hat - Subaru STI 04-17

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 aluminum 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 aluminum hats. The use of aerospace-grade aluminum 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 the disc to the hub via the aluminum 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-us
