This work describes the development process of the unsprung components of a formula-styled race car that participated in the 2018 Formula SAE Italy and Formula Student Spain competitions representing the Politecnico di Torino. The report is mostly focused on the mechanical design of structural elements, considering performance and packaging constraints and the ease of manufacturing and assembling (DFMA). A comprehensive description of the design process is included, highlighting the integration between the different disciplines and technical divisions of the PoliTo Racing Team (Squadra Corse Polito), with a focus on the wheel uprights as the element in which converge the transmission, cooling, suspension and brake systems.
