DBA Front 4000 XS Brake Rotors Xtreme Pads for Toyota Aristo JZS147 Soarer JZZ30

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.

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 T3 slot, the XS Gold is a popular alternative for show cars.

SURFACE DESIGN - 1
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 - 2
Painted non friction areas to prevent rust and enhance appearance.

BI DIRECTIONAL USE - 3
Symmetrical slotting and/or drilling for universal use.

HIGH CARBON ALLOYED IRON - 8
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 - 9
Unique Kangaroo Paw vane design for up to 20% better heat dissipation, increasing braking effectiveness and prolonging brake life.

THERMAL STABILITY PROFILING - 4
Heat treatment cycles realign the microstructure of the iron, resulting in increased rotor stability and durability.

THERMAL EFFICIENCY - 5
Centre split core castings for increased heat transfer and thermal efficiency.

CBN - 6
CBN (Cubic Boron Nitride) machine turned finish, minimising disc thickness variation and the potential for pad "knock" and resulting premature wear.

THERMOGRAPHIC HEAT PAINT - 7
Paint markings change colour at specific temperature thresholds to assist with the monitoring of braking temperatures and rotor fatigue.

*Some variants may not contain all features.

XTREME PERFORMANCE brake pads have been designed for drivers seeking high initial bite and friction consistency from low to high temperatures. The XP range is for heavy duty applications, where higher friction levels are required to safely brake under extreme conditions.DBA recommends XTREME PERFORMANCE brake pads for street performance and police pursuit vehicles, as well as club track days, heavy towing and upgraded 4WDs.DBA recommends use with T3 slotted rotors in the 4000 & 5000 SERIES for best stopping performance.
