Porsche 718 Cayman S Brake Rotor (1) - Front - DBA - 5000 Series HD - 2017. A direct-replacement front rotor from DBA’s 5000 Series HD line designed for drivers seeking a durable, high-performance composite rotor with an OE-style smooth finish.

The DBA 5000 Series HD is a composite two-piece design that pairs high-carbon cast-iron rotor rings with aerospace-grade T6061-T6 aluminum hats, fastened using National Aerospace Standards (NAS) bolts and crimp nuts. This construction reduces unsprung weight compared to one-piece cast rotors, improves heat management by isolating hub temperatures, and maintains uniform radial disc expansion under heavy use. The HD variant offers the smooth, OE-style rotor face preferred by owners who do not want slotted, cross-drilled, or dimpled surfaces but still require the enhanced thermal and structural characteristics of the 5000 Series.

• Composite 2-piece design: high-carbon cast-iron ring + T6061-T6 aluminum hat
• NAS bolts and crimp nuts for secure, serviceable assembly
• Reduced unsprung weight and improved heat isolation
• Smooth OE-style rotor face (5000 Series HD)
• Suitable for high-performance street, track day, club racing, and rally use
