The aluminium hat of the Composite, Floating and Dual Cast discs and the steel hat of the Co-cast and Lightweight discs allow a weight reduction of the disc that can range from 15 to 30% compared to an integral one of the same dimensions.
If compared to the mass of the vehicle, this reduction may seem marginal. However, it actually has a significant impact on consumption, performance and handling of the car, since the disc is part of the vehicle’s unsprung masses.
