DBA 4000 XD Drilled/Dimpled Rotor PAIR

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.

• Surface Design Slots and/or chamfered drill holes facilitate the exit of friction dust and gasses, for a quieter and more responsive pedal feel.*
• Anti Rust Painted non-friction areas to prevent rust and enhance appearance
• BI-Directional Use Symmetrical slotting and/or drilling for universal left/right use.*
• Thermal Stability Profiling Heat treatment cycles realign the microstructure of the iron, resulting in increased rotor stability and durability.
• Thermal Efficiency Centre-split core castings for increased heat transfer and thermal efficiency.
• CBN Cubic Boron Nitride (CBN) machine turned finish, minimising disc thickness variation and the potential for pad "knock" and resulting premature wear.
• Thermographic Heat Paint Paint markings change colour at specific temperature thresholds to assist with the monitoring of braking temperatures and rotor fatigue.
• High Carbon Alloyed Iron Formulation allows for optimal interaction with DBA’s thermal stability profiling (TSP). Increases the capacity of the rotor to handle constant and extreme heat over prolonged periods.
• Kangaroo Paw Unique Kangaroo Paw vane design for up to 20% better heat dissipation, increasing braking effectiveness and prolonging brake life.*
