4000 Series XS Gold Rear Brake Rotor

The DBA 4000 Series XS Gold Rear Brake Rotor is engineered to provide enhanced braking performance beyond standard Original Equipment levels. This single-piece, direct replacement rotor is cast from high carbon alloyed iron, treated with Thermal Stability Profiling (TSP) for increased durability under intense heat and stress. The rotor features DBA's unique non-directional cross-drilled and slotted surface design, which allows for better exit of friction dust and gases, contributing to a quieter and more responsive pedal feel. The XS Gold variant adds an attractive gold finish to the rotor hub, making it a popular choice for show cars. Key specifications include a 316mm outer diameter, 20mm thickness, and a minimum thickness of 18mm. It has a centering diameter of 58mm and features a 5-hole bolt pattern with a dual pitch circle diameter of 100mm and 114.3mm. DBA specifies that drilled rotor configurations are not recommended for heavy off-road or track day usage. This rotor is specifically designed for the 2004-2007 Subaru WRX STI models.
