DBA 5000 Series 2015-2017 STI

The DBA 5000 series is a direct replacement two-piece disc brake rotor, designed for drivers seeking performance braking. The DBA 5000 series disc rotors consists of two main components: the aluminum center hat and the cast iron disc rotor. These two components are bolted together with NAS (National Aerospace Standard) bolts and lock nuts, hence the term 'two-piece' rotor. The main advantage of a two-piece rotor (with aluminum hat), is the ability to allow the cast-iron disc rotor to expand and contract uniformly as the temperature rises and falls during brake application. The benefits of this is minimal distortion and warping of the cast-iron disc rotor. The Aluminum mounting center hat is made from super-light 6061-T6 Aluminium material, as used in aircraft structural design. The thermal conductivity and high strength of hat allows it to handle large temperature changes. All DBA T3 5000-series rotors are slotted; slotting limits the possibility of glazing your brake pads and allows b
