DBA 4000 Series T3 Slot Front Rotor

The Stillen DBA 4000 Series T3 Slot Brake Rotor is a high-performance aftermarket brake rotor engineered for drivers seeking braking capabilities beyond standard OE levels. Constructed from premium high carbon alloyed iron, these rotors are subjected to Thermal Stability Profiling (TSP) to ensure they can withstand the intense heat and stress generated during demanding braking applications, time after time. This rotor features DBA's patented Kangaroo Paw ventilation system, which utilizes 144 diamond and teardrop-shaped pillars. The T3 slot profile is Tri-symmetrical, designed to reduce noise and vibration while maximizing pad-to-rotor contact for improved braking performance. The surface type is slotted, and the rotor is vented. Key technical specifications include an outside diameter of 320 mm, an overall height of 48.5 mm, a nominal thickness of 25 mm, and a center hole diameter of 72 mm. It has a lug hole quantity of 5. This DBA42962S rotor is specifically designed as a direct replacement for the 2007-2011 Mazda 3, with a noted fitment for the MAZDASPEED submodel.
