Mazda Miata Brake Rotor (1) - Rear - DBA - 4000 Series HD - 01-05. This rear replacement rotor from DBA brings the 4000 Series HD construction to Miatas from 2001–2005, offering a plain (non-drilled/non-slotted) OE-style finish for drivers who want improved thermal performance without changing the rotor appearance.

Cast from XG-150 high carbon alloyed iron and processed with DBA’s Thermal Stability Profiling (TSP), this rotor is built to manage repeated high-heat braking events. The Kangaroo Paw ventilation uses 144 diamond and teardrop patterned pillars to increase surface area and improve cooling compared to traditional straight vane designs, helping reduce fade during demanding use. The 4000 Series HD variant maintains a smooth, OE-style face while incorporating thermographic paint markings (THGP) and moisture-proof corrosion protection packaging. It is a direct replacement fit for the rear brake on compatible Miata models.
