DBA 04-17 Subaru WRX STi Rear Crossdrilled & Slotted 4000 XS Series Rotor - 43051XS-10

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.

Product Features:

• Surface Design: Symmetrical 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, or full En-shield coating to protect the rotor and alleviate the need for pre-installation cleaning.
• 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.
• Thermographic Heat Paint: Paint markings change colour at specific temperature thresholds to assist with the monitoring of braking temperatures and rotor fatigue.
• CBN: CBN (Cubic Boron Nitride) machine turned finish, minimising disc thickness variation and the potential for pad "knock" and resulting premature wear.
• 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.
