DBA 5000 Series 2-Piece Composite Brake Rotors with Aluminum Hats

DBA 5000 Series 2-Piece Composite Brake Rotors with Aluminum Hats High-performance, lightweight brake rotors engineered for street, track day and competition use. The DBA 5000 Series builds on the proven 4000 Series design with aerospace-grade materials and advanced thermal management. Composite 2-piece construction: high-carbon cast-iron rings bonded to T6061-T6 aluminum hats for optimal strength and reduced weight. Superior heat control: aluminum hats minimize heat transfer to the hub and promote uniform radial disc expansion for consistent braking under stress. Aerospace-grade hardware: assembled with National Aerospace Standards (NAS) bolts and crimp nuts for long-term durability and reliability. Serviceable design: available as complete assembled rotors or as replaceable hats and flat disc rings so you can refresh wear surfaces without replacing the entire assembly. Applications: recommended for high-performance street vehicles, track day drivers, club racing and rally competitors. Experience reduced unsprung weight, improved thermal stability and the proven braking technology of DBA in a lightweight, serviceable package designed for demanding driving environments.
