The DBA 4000 Series slotted rotor is a direct-replacement performance rotor that combines high-carbon, heat-treated iron with patented Kangaroo Paw ventilation and tri-symmetrical slotting for improved cooling and consistent braking. For 2004–2005 Mazda 3 2.3L (except MazdaSpeed) front fitment, the T3 bi-directional slot design enhances pad bite and helps manage heat for longer, more predictable rotor life.
