Race car aerodynamics primarily aims to reduce the forces of drag and to increase the down forces for high-speed cornering while ensuring stability. Aerodynamic coefficients of a body will determine the combined effect of drag and down forces on straight line speed and cornering speed. This paper focuses on the selection of optimum coefficients that strike a balance between the values of the forces mentioned above for a given racetrack and details the canonical implementation of CFD using Simscale software simulations. The results infer the post processed data of CFD simulations using Paraview software and compare the lap time of a Formula Student vehicle, with and without aerodynamic package.
