function	Description	Advantage
T3 Slot 48 precise CNC machined 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 to escape through the universal slot design	Increases the uniformity and efficiency of every braking process
		No different left and right brake discs required
Kangaroo Paw – 144 Diamond and Tear Drop column ventilation system	The increased surface area leads to better heat dissipation	Minimizes brake fade and increases braking effectiveness
	The increased surface area leads to better heat dissipation	Extends the life of pads and brake discs. Reduces mechanical damage and associated costs
XG150 High Carbon Alloy Iron	Increased thermal capacity allows the brake disc to handle extreme heat for extended periods	Minimizes deformation and cracking and extends the life of the brake disc
Thermal stability profile	Special development that is tailored to the DBA’s TSP procedure	Minimizes deformation and cracking and extends the life of the brake disc
Thermographic temperature monitoring	Heat color markers change color at certain temperature thresholds	Provides the driver with a clear indication of peak brake temperatures
	If the temperature thresholds are exceeded, the color markings permanently change color	Allows the driver to monitor brake disc fatigue and decide whether to replace the brake discs and assist dealers with warranty claims
Paint protection on friction-free surfaces	Reduces corrosion	Prevents unsightly rust formation
	Improves appearance	Increases the value of the product
