BRAKE ROTORS - 4000 Series

4000 Series disc brake rotors are a direct replacement single piece brake rotor, designed for drivers seeking upgraded performance braking above and beyond standard OE levels.

Cast from high carbon alloyed iron and undergoing Thermal Stability Profiling, DBA's metallurgy can handle the increased stress and heat generated under intense braking applications, time and time again.

Featuring DBA's Kangaroo Paw ventilation that implements a series of 144 diamond and teardrop patterned pillars, DBA achieves up to a 30% increase in surface area and 20% improvement in cooling efficiency (as compared to a traditional straight vane design).

Feature

• Symmetrical slots and/or chamfered drill holes facilitate the exit of friction dust and gasses, for a quieter and more responsive pedal feel.
• Painted non friction areas to prevent rust and enhance appearance.
• Symmetrical slotting and/or drilling for universal left/right use.
• Heat treatment cycles realign the microstructure of the iron, resulting in increased rotor stability and durability.
• Centre-split core castings for increased heat transfer and thermal efficiency.
• CBN (Cubic Boron Nitride) machine turned finish, minimising disc thickness variation and the potential for pad 'knock' and resulting premature wear.
• Paint markings change colour at specific temperature thresholds to assist with the monitoring of braking temperatures and rotor fatigue.
• 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.
• Unique Kangaroo Paw vane design for up to 20% better heat dissipation, increasing braking effectiveness and prolonging brake life.

*Some variants may not contain all features

XS Gold

XS Gold provides all the benefits of 4000 Series, with a premium non directional cross drilled and slotted design, plus an attractive gold finish on the rotor hub.
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 T 3 slot, the XS Gold is a popular alternative for show cars.
Drilled rotor configurations are not recommended for heavy off-road or track day usage.
