Returns Exchanges will incur restocking and freight fees or may be denied in certain circumstances. DBA's 4000 Series XD variant features DBA's non directional cross drilled and dimpled rotor design. The XD finish provides additional cooling benefits above the HD spec, along with enhanced sports looks. The DBA mix of dimples and drilled holes provides enhanced rotor structural support above transitional cross drilled techniques. DBA recommends a T3 slot for high performance applications. Features: 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 and prolongs service life for both pads and rotors. Reduces mechanical damage and associated costs XG150 High Carbon Alloyed Iron An increase in thermal capacity property allows the rotor to handle constant extremes of heat over extended periods of time which minimises warping and cracking and prolongs the service life of the rotor. Special formulation designed to respond to DBAs TSP process. Thermographic Temperature Monitoring Heat paint markings change colour at specific temperature thresholds offers the driver a clear indication of peak braking temperatures. When temperature thresholds are exceeded paint markings will permanently change colours allowing the driver to monitor rotor fatigue and decide on rotor replacement and to assist resellers with warranty claims. Paint protection on non friction areas Reduces corrosion, enhances appearance, stops any unsightly rust formation, adds value to the product.
