DBA 5000 Series XS Front Brake Rotor Ring

The Stillen DBA52314.1XS is a front brake rotor ring, specifically designed as a direct replacement for drivers seeking upgraded braking performance beyond standard OE levels. It belongs to the DBA 5000 Series XS line, featuring a cross-drilled and slotted surface for improved heat dissipation and stopping power. Constructed from high carbon alloyed iron, this rotor has undergone Thermal Stability Profiling (TSP). This process allows the metallurgy to withstand the increased stress and heat generated during intense braking applications, ensuring consistent performance over time. The rotor incorporates DBA's patented Kangaroo Paw ventilation, which uses 144 diamond and teardrop-shaped pillars to achieve up to a 30% increase in surface area and a 20% improvement in cooling efficiency compared to traditional straight vane designs. The vented rotor has an outside diameter of 355mm, a nominal thickness of 30mm, and a discard thickness of 32mm. It also features a 162mm center hole diameter and 12 lug stud holes. This DBA rotor ring is compatible with a range of Infiniti and Nissan vehicles, including the 2008-2012 Infiniti G37, 2009-2010 Infiniti FX50, and various 350Z and 370Z models. Specific fitment notes indicate requirements such as "Sport Perf Brakes; Aluminum Calipers" for certain Nissan models, "Sport Package" for some Infiniti M series, and distinctions for "Sport, Hybrid Sport" or "Sport, Red Sport" trims on the Q50, Q60, and Q70 models. For the 2009-2010 Infiniti FX50, it fits the FX50 (S51 Model). The G37 fitment varies by year and trim, with specific mentions for Base, Journey, Sport, and IPL models, as well as AWD variants.
