Fitment Notes

• Rear rotor position only. Does not replace front rotors.
• Sold individually. Order 2 for a complete rear axle set.
• Verify current rear rotor diameter is 279.5mm before ordering. Some early BK models may differ by trim configuration.

Features

• T2 bi-directional curved slot design with 32 CNC-machined bi-symmetrical slots for consistent gas and dust evacuation
• Universal slot design eliminates the need for separate left and right rotor configurations
• Patented Kangaroo Paw ventilation system with 144 diamond and teardrop pillars for improved passive cooling
• CBN (Cubic Boron Nitride) machine-turned friction surface for tighter tolerances and reduced disc thickness variation (DTV)
• Cast from DBA's proprietary XG-150 high-carbon iron alloy for superior resistance to heat warping
• Slotted design increases pad bite, reduces pad fade, and extends pad and rotor service life
• Reduced noise profile compared to traditional straight-slot designs thanks to curved slot geometry
• Manufactured to above-OEM tolerances - engineered and produced in Australia

Product Description

The DBA DBA2957S is a Street Series T2 Slotted rear brake rotor designed as a direct OE replacement for the Mazda 3 (BK/BL) and Mazdaspeed 3, spanning model years 2004 through 2013. Built from DBA's proprietary XG-150 high-carbon iron alloy and finished with Cubic Boron Nitride (CBN) tooling, this rotor offers exceptional dimensional precision and thermal stability right out of the box - no break-in warping issues commonly seen with lower-grade alternatives.

The T2 slot design channels brake dust and gases away from the pad surface, maintaining consistent bite and reducing the risk of fade during spirited or heavy use. DBA's Kangaroo Paw ventilation pillars maximize heat dissipation without sacrificing rotor mass or structural rigidity. The bi-symmetrical, universal slot pattern means no directional confusion during installation - one part number works for both sides. Ideal for daily drivers, commuters, and light performance use on FWD Mazda 3 and Mazdaspeed 3 platforms.
