4000 Series Standard Rear Brake Rotor

The DBA 4000 Series Standard Brake Rotor is a direct-replacement rear brake rotor engineered by Disc Brakes Australia (DBA) for drivers seeking enhanced braking performance beyond standard Original Equipment (OE) specifications. It is constructed from high-carbon alloyed iron and features Thermal Stability Profiling (TSP) to ensure consistent performance and durability under demanding braking conditions. DBA's performance series rotors, including this model, often utilize the patented Kangaroo Paw ventilation system. This enhanced cooling helps to dissipate heat more effectively, reducing the risk of brake fade during aggressive use. This specific rotor, DBA42961, is designed for the rear application and is compatible with the 2006-2007 Mazda 6, specifically the Mazdaspeed 6 model. The rotor has a smooth surface type and is a solid rotor design. Key technical specifications include an outside diameter of 314 mm, a nominal thickness of 11 mm, a discard thickness of 11 mm, an overall height of 41 mm, a center hole diameter of 72 mm, and 5 stud/lug holes.
