DBA 4000 HD ROTORS PAIR – Ford Focus RS LZ – Brembo 350 x 25mm

The DBA 4000 Series HD is the ideal OE-style rotor upgrade for your Brembo-equipped Ford Focus RS LZ. Featuring a smooth rotor face, the HD variant delivers all the thermal and structural benefits of DBA’s high-performance 4000 Series without the aggressive bite or noise of slotted or drilled designs. Perfect for street enthusiasts or classes where slotted rotors are restricted.

Constructed using DBA’s high carbon alloy and treated with Thermal Stability Profiling (TSP), the 4000 HD rotor improves resistance to warping and cracking under sustained heat. Kangaroo Paw ventilation increases cooling efficiency, while Thermographic Temperature Monitoring (TTM) markings offer a visual reference for rotor heat thresholds — making it ideal for performance road driving and occasional track days.
