The analytical calculation of springing and damping parameters of the vehicle is worked through. Also, the dynamic performance of the vehicle is evaluated through multibody dynamics simulation tools. Firstly, the goals that have been set at the beginning of the suspension system development process are shown together with the design limitations. Most of the limitations are set by the Formula Student competition rulebook. The suspension system's kinematic characteristics are shown and their impact on vehicle performance is reviewed. The springing and damping parameters are calculated analytically. Furthermore, their impact on the maneuvrability and the vehicle response is explained. Vehicle models which are created in Adams Car and CarSim Mechanical Simulation are validated through the comparison of driving procedures simulated in them. Finally, the impact of springing and kinematic settings on vehicle performance is analyzed through driving procedures simulated in the Adams Car multibody dynamics tool
