Porsche 911 GT3 Brake Rotor (1) - Front - DBA - 5000 Series HD - `04-`08. This is a direct-replacement front rotor ring from DBA’s 5000 Series HD, designed as a composite two-piece unit for Porsche 911 GT3 models from the '04–'08 range.

The 5000 Series HD combines a high-carbon cast-iron friction ring with an aerospace-grade T6061-T6 aluminum hat, assembled with National Aerospace Standards (NAS) bolts and crimp nuts. Compared to a one-piece rotor, this design reduces unsprung weight and improves heat management by allowing more uniform radial expansion of the disc and reducing heat transfer to the hub. The HD variant provides a smooth OE-style rotor face for owners who prefer no slots, cross-drilling, or dimpling while retaining the performance characteristics of the 5000 Series. Suitable for high-performance street use, track days, club racing and rally applications, this rotor ring is offered as a replacement ring or as part of a complete assembly when needed.

Features

• Composite two-piece design: high-carbon cast-iron ring + T6061-T6 aluminum hat
• NAS bolts and crimp nut fastening for aerospace-grade assembly
• Smooth OE-style HD finish—no slots, drilling, or dimples
• Reduced unsprung weight and improved thermal behavior
• Direct replacement for 2004–2008 Porsche 911 GT3 front applications

This rotor ring is a practical upgrade for enthusiasts seeking improved thermal control and reduced rotating mass without changing rotor surface style.
