At the Frankfurt IAA in 1999, the carbon ceramic brake disc had its world premiere. The use of high-tech material had revolutionized brake technology: compared to the conventional gray cast iron brake disc, the carbon ceramic brake disc weighed about 50 percent less reducing unsprung mass by almost 20 kilograms. Other important advantages are: improved brake response and fade data, high thermal stability, no vibration, excellent pedal feel, improved steering behavior, high abrasion resistance and therefore longer wear of life and the advantage of almost avoiding brake dust. At first, Porsche AG built the carbon ceramic brake disc in 2001 on the 911 GT2 as standard equipment. Since then, other premium brands have used the advantages of this innovative braking technology for greater safety and comfort. These are, for example, sports cars and luxury limousines from Audi, Bentley, Bugatti and Lamborghini.
