DBA 2004 Pontiac GTO Front 5000 Series Replacement Ring

This direct-replacement front rotor is the DBA 5000 Series HD option designed for drivers who want the proven 5000 Series technology with a smooth OEM-style finish. The DBA 5000 Series is a composite two-piece design that pairs high-carbon cast-iron rings with aerospace-grade T6061-T6 aluminum hats, joined with National Aerospace Standards (NAS) bolts and crimp nuts. The 5000 Series HD variant retains the performance characteristics of the 5000 line while providing a flat, non-slotted, non-drilled surface preferred by many street and track owners. The aluminum hat reduces unsprung weight and helps manage disc-to-hub heat transfer, while the cast-iron ring provides consistent braking surface and wear characteristics. Suitable for high performance street use, track day and club racing or rally applications, the 5000 Series HD offers a balance of durability and thermal control without added surface machining.
