Ford Focus Brake Rotor (1) - Front - DBA - 5000 Series HD - '16-'18. A direct-replacement, two-piece composite rotor designed to give your Focus improved thermal control and reduced rotating mass compared with a one-piece cast rotor.

This DBA 5000 Series HD rotor uses high-carbon cast-iron friction rings bonded to aerospace-grade T6061-T6 aluminum hats, fastened with National Aerospace Standards (NAS) bolts and crimp nuts. The 5000 Series shares the proven performance technology of the 4000 Series while the HD variant retains a smooth OE-style disc face for drivers who prefer a non-slotted, non-drilled surface. The aluminum hat lowers unsprung weight, helps regulate radial expansion of the disc under load, and reduces heat transfer into the hub — benefits appreciated by high-performance street drivers and track-day enthusiasts.

Features

• Two-piece composite design: high-carbon cast-iron ring + T6061-T6 aluminum hat
• NAS-spec bolts and crimp nuts for secure assembly
• HD finish: smooth, OE-style rotor face (no slots or drill holes)
• Reduced unsprung weight and improved heat management
• Direct replacement for front brakes on compatible 2016–2018 Ford Focus models
