DBA T3 5000 Series Replacement Brake Rotor DBA52935.1S, 330 x 28 mm

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. 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.

The DBA T3 5000 Series Replacement Brake Rotor is a high-performance composite two-piece direct-replacement rotor designed for demanding street, track day, club racing, and rally applications. Part number DBA52935.1S is engineered as an AP Racing replacement for CP3580-2898 and CP3580-2899 applications, delivering reliable braking performance under strenuous conditions.

DBA combines a high-carbon cast-iron rotor ring with an aerospace-grade T6061-T6 aluminum hat. This construction reduces unsprung weight compared with conventional one-piece rotors while improving heat management and limiting heat transfer from the disc to the hub. The rotor assembly uses National Aerospace Standards bolts and crimp nuts to provide secure, durable fastening during repeated high-temperature braking cycles.

As part of the DBA T3 5000 Series, this replacement rotor incorporates performance technology from the 4000 Series while adding the benefits of a lightweight aluminum hat and uniform radial disc expansion. It is intended for use with compatible DBA 5000 Series components and may support replacement of the flat disc ring while reusing an existing DBA 5000 Series hat, subject to application compatibility. Verify vehicle, caliper, and rotor fitment before installation.
