DBA 4000 Series Front Brake Rotor

The Stillen DBA 4000 Series Standard Brake Rotor is engineered for drivers seeking performance braking upgrades beyond factory specifications. Manufactured by Disc Brakes Australia, this rotor is constructed from high carbon alloyed iron, chosen for its ability to withstand higher stress and heat loads during demanding driving conditions. The material undergoes Thermal Stability Profiling (TSP) to ensure consistent performance and longevity. This rotor incorporates DBA's innovative Kangaroo Paw ventilation system. This enhanced cooling is crucial for preventing brake fade and maintaining optimal braking performance, especially during spirited driving or repeated hard stops. With an outside diameter of 334 mm, a nominal thickness of 30 mm, and a vented rotor type, the DBA42720 is designed as a direct replacement for specific Lexus models. The precise specifications, including a 62.04 mm center hole diameter and 5 lug hole quantity, ensure an OE-compatible fit for straightforward installation. The rotor surface is smooth, providing a solid foundation for brake pad engagement. This DBA 4000 Series rotor is compatible with a range of Lexus vehicles, including the 2007-2011 GS350, 2006-2007 GS430, 2007-2010 GS450h, 2008-2010 GS460, and various IS300 and IS350 models from 2016 to 2022. Specific fitment notes, such as 'Canada Spec' for certain IS350 models and 'F Sport' for the 2022 IS300 and IS350, indicate particular configurations that require attention for accurate application.
