Specifications
Part Details:
Fitment note: this rotor requires Brembo brake calipers, standard equipment on every 2004-2012 STI. If installing on any other application, confirm Brembo calipers are present before ordering.
The DBA 4000 Series T3 is DBA’s most advanced one-piece rotor, built on the foundation of their T2 slot design with additional precision CNC machined tri-symmetrical slots for an even quieter, smoother, more responsive brake pedal feel. The T3 slotting increases exit points for brake pad friction dust and gases to escape, keeping the pad surface cleaner and more consistent under hard use. Constructed from high-carbon, heat-treated iron with DBA’s patented Kangaroo Paw ventilation for improved heat dissipation and reduced rotor cracking under repeated hard braking.
A direct, single-piece replacement rotor designed for drivers seeking real performance braking gains over the standard OE rotor.
