Returns Exchanges will incur restocking and freight fees or may be denied in certain circumstances. DBA's X Gold provides all the benefits of Street Series, with a premium non directional cross drilled and slotted design, plus an attractive gold finish on the rotor hub of most models (Black offered otherwise). The introduction of our unique cross drilled and slotted design increases the number of exit points, allowing more brake pad friction dust and gases to escape through both the cross drilled holes and slots, resulting in better braking performance. While providing a similar performance benefit to the T2 slot, the X Gold is a popular alternative for open wheel and show cars. We recommend the T2 slot design for more intensive braking applications. Features (Where Applicable): Kangaroo Paw 144 diamond and tear drop pillar ventilation system Increased surface area resulting in greater heat dissipation which minimises brake fade and increases braking effectiveness CBN (Cubic Boron Nitride) machine turned Reduced DTV (Disc thickness variation) and parallelism which provides less occurrence of brake shudder or brake pedal "judder".
