DBA 13-15 Ford Focus ST(w/320mm Front Rotor) Front 5000 Series Slotted Ring

DBA 5000 Series HD Front Brake Rotor (1) for Ford Focus ST ('13-'18) is a direct replacement, two-piece composite rotor designed to offer improved heat management and reduced unsprung weight over a one-piece rotor. The HD variant provides a smooth OE-style finish for drivers who prefer no slots, dimples, or cross-drilling. This rotor pairs high carbon cast-iron rings with aerospace-grade T6061-T6 aluminum hats, joined using National Aerospace Standards (NAS) bolts and crimp nuts. The 5000 Series shares the proven performance technology of the 4000 Series while adding weight savings and better thermal isolation between the disc and hub. DBA offers complete assemblies and replacement rings so you can re-use hats or refresh rings as needed. Recommended for high-performance street use, track day, club racing and rally applications where consistent braking and heat control matter.
