4000 Series Cross-Drilled & Slotted Rotor

The Disc Brakes Australia 4000 Series Rotor (DBA42028BLKXS) is a high-performance, single-piece brake rotor engineered for drivers who demand enhanced braking capabilities beyond standard equipment. This rotor is part of the 4000XS series, designed to offer superior performance for aggressive street driving, motorsports, and off-road applications. Constructed from high-carbon, heat-treated iron, the DBA42028BLKXS rotor features a patented Kangaroo Paw ventilation system, which provides increased surface area and improved heat dissipation compared to traditional rotor designs. The uni-directional, cross-drilled, and slotted surface is optimized to cut through gases and remove debris, ensuring consistent braking performance and reducing the risk of brake fade. The rotor also sports a distinctive black painted finish and a black hat for a performance aesthetic. As a direct replacement rotor, the DBA42028BLKXS is designed for straightforward installation. It is compatible with the 2008-2009 Pontiac G8 GT model equipped with the 6.0L (364ci) V8 engine.
