Aerodynamics is a branch of fluid mechanics associated with the fluid dynamics and fluid flow in and around the bodies. It involves the investigation of the fluid flow pattern measuring the required forces and other parameters such as velocity, pressure and density. In this paper we analysed a specified base car model with different combinations of connected diffusers, spoilers and bumpers, and with those attached, different design results are analysed in low speed wind tunnel and validated using Star-CCM+. Parameters that lead drag values closer to the experiment with less memory and computational time are identified. These investigations are carried out in star-CCM+ CFD package; however, the results can be applied to similar CFD Acodes.
