DBA 5000 Series 2-Piece Drilled Rotors with Aluminum Hats

DBA 5000 Series 2-Piece Drilled Rotors with Aluminum Hats High-performance composite 2-piece brake rotors engineered for street, track day and club racing. DBA's 5000 Series combines proven 4000 Series technology with lightweight aerospace-grade components to deliver superior stopping power, heat management and longevity. Premium materials: high-carbon cast-iron rings bonded to T6061-T6 aerospace-grade aluminum hats for strength and thermal control. Reduced unsprung weight: aluminum hats lower rotating mass for improved suspension response and handling. Improved heat management: uniform radial disc expansion via cast-iron rings and reduced heat transfer to the hub thanks to aluminum hats. Durable fasteners: National Aerospace Standards (NAS) bolts and crimp nuts ensure secure, reliable assembly. Serviceable design: available as complete assemblies or as replacement hats and flat discs, allowing reuse of hats with new rings. Applications: ideal for high-performance street cars, track use, club racing and rallying.
