Rear Brake Rotor Ring, Cross-Drilled and Dimpled

The Stillen DBA52323.1EXD is a rear brake rotor ring from DBA's 5000 Series, engineered for drivers seeking enhanced braking performance beyond standard OE levels. These performance rotors are cast from high carbon alloyed iron, a material chosen for its ability to withstand increased stress and heat generated during intense braking applications. DBA's rotors undergo Thermal Stability Profiling (TSP) to ensure metallurgical integrity under demanding conditions. This specific model, the DBA52323.1EXD, features a vented rotor design with a cross-drilled and dimpled surface. This design helps to vent heat and gases, leading to improved brake bite and reduced fade, making them ideal for wet climates and spirited driving. The rotor also incorporates DBA's patented Kangaroo Paw ventilation system, which utilizes diamond and teardrop-shaped pillars to increase surface area and improve cooling efficiency compared to traditional straight vane designs. Technical specifications include an outside diameter of 380mm, a nominal thickness of 30mm, and a stud/lug hole quantity of 8. The disc brake rotor is designed as a direct replacement component for specific Nissan GT-R models and their associated years. Fitment notes indicate specific production date ranges and exclusions for Nismo models on certain years, as well as specifying Brembo designs for 2012, 2015-2016, 2018-2019, and 2021 models.
