The reduction of the vehicle weight and unsprung masses has been one of the primary objectives of car manufacturers in recent years, to handle the needs for greater reduction of consumption and emissions.
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.
