4000 Series XD Front Brake Rotor

The DBA 4000 Series XD is a front brake rotor designed to enhance braking performance and aesthetics. It features DBA's proprietary non-directional cross-drilled and dimpled rotor design. The XD finish not only adds to the sports appearance but also provides improved cooling capabilities over the HD specification. Constructed with a mix of dimples and drilled holes, this rotor offers enhanced structural support compared to standard cross-drilled techniques. The technical specifications include a 340mm outer diameter, a 53mm height, and a 30mm brake disc thickness with a minimum thickness of 28mm. It has 10 holes, a centering diameter of 58.02mm, and a pitch circle diameter accommodating both 100mm and 114.3mm patterns. The vane design is R KP Vents, and it weighs 10.82kg. While offering significant performance and aesthetic upgrades, it is important to note that drilled rotor configurations are not recommended for heavy off-road or track day usage. For optimal fitment, this rotor is specifically designed for the 2018-2021 Subaru STi and the 2024+ Subaru WRX TR/TS models.
