The aim of this paper was to determine the differences in the designed and manufactured model of a suspension. A set of key parameters was compared, including camber and toe in angles and their change w.r.t wheel travel, as well as the motion ratio. It also focused on the possibility of accurately determining the suspension system kinematics using affordable measuring devices available on the market. First, the design process, main goals and project assumptions were briefly described. Next, the CAD model and manufacturing process was presented. Finally, the measurements of both computer and real model were performed. The obtained results were compared and a significant difference between models was observed. The reason of such variation could not be determined unambiguously, as there were numerous factors that could potentially influence the results. Moreover, it was proven that accurate determination of kinematics is impossible using the given set of measuring devices.
