DBA 5000 Series T3 Slotted 2-Piece Front Brake Rotor Assembled for Select Nissan & Infiniti 2008-2022

Fits select 2008-2022 Infiniti (G37, Q50, Q60, M37, FX50) and Nissan (350Z, 370Z) models. This DBA 5000 Series assembly is a high-performance, two-piece direct replacement rotor designed for track days, rally, and high-performance street use.

By combining a high-carbon cast iron ring with a T6061-T6 aerospace-grade aluminum hat, the 5000 Series significantly reduces unsprung weight. This design improves handling and reduces heat transfer from the disc to the hub, preventing bearing wear and ensuring uniform radial expansion under extreme thermal loads. The two-piece construction also offers long-term cost savings, as the aluminum hats can be reused with DBA replacement rings. Each rotor is factory-assembled using National Aerospace Standards (NAS) bolts and crimp nuts for maximum structural integrity.
