DBA 4000 Series Rear Brake Rotor

Disc Brakes Australia (DBA) manufactures the 4000 Series Standard Brake Rotor, a performance aftermarket brake rotor designed to exceed standard OE capabilities. This rotor is constructed from high carbon alloyed iron and has undergone Thermal Stability Profiling (TSP) to withstand the increased stress and heat generated during intense braking. It incorporates DBA's patented Kangaroo Paw ventilation system, which uses 144 diamond and teardrop pillars. This design provides up to a 30% increase in surface area and a 20% improvement in cooling efficiency compared to traditional straight vane designs. The DBA42309 is a vented rotor with a smooth surface type. Its technical specifications include a 308 mm outside diameter, 62 mm overall height, 16 mm nominal and discard thickness, and a 68 mm center hole diameter. It has a 5-stud/lug hole quantity. This rear brake rotor is compatible with a wide range of Infiniti and Nissan models from 2003 to 2022. Specific fitment notes include compatibility with Standard Brakes and Iron Calipers for certain Nissan 370Z and 350Z models, and exclusions for Sport Brake Packages on some Infiniti G25, G37, and M45 models. It is also noted as compatible with 4WD on the 2015 Infiniti Q40. Careful consultation of the fitment details is recommended to ensure proper application for your specific vehicle.
