Data:

Function	Description	Advantage
T3 Slot 48 precision CNC-milled slots	Tri-symmetrical slots dampen vibrations and noise	A softer, more responsive and smoother brake pedal feel
	Increased number of exit points for brake pad friction gases that escape through the universal slot design	Increases the evenness and efficiency of every braking process
		No different brake discs required on the left and right
Kangaroo Paw - 144 Diamond and Tear Drop column ventilation system	The increased surface area leads to better heat dissipation	Minimizes brake fade and increases the braking effect
	The increased surface area leads to better heat dissipation	Extends the service life of pads and brake discs. Reduces mechanical damage and the associated costs
XG150 Alloyed iron with high carbon content	Increased thermal capacity enables the brake disc to cope with extreme heat for longer periods of time	Minimizes deformation and cracking and extends the service life of the brake disc
Thermal stability profile	Special development tailored to the DBA TSP process	Minimizes deformation and cracking and extends the service life of the brake disc
Thermographic temperature monitoring	Heat color markings change color at certain temperature thresholds	Provides the driver with a clear display of the peak brake temperatures
	If the temperature thresholds are exceeded, the color markings change color permanently	Enables the driver to monitor brake disc fatigue and decide whether to replace the brake discs and supports dealers with warranty claims
Paint protection on frictionless surfaces	Reduces corrosion	Prevents unsightly rust formation
	Improves the appearance	Increases the value of the product
