This paper goal is to identify the real influence of the torsional stiffness of a Baja SAE prototype in its dynamic performance. Its main objective is to analyze several data from lateral load transfer of the vehicle considering different configurations for certain parameters. The chassi is the component that provides coupling for the suspension system, therefore it has direct influence in suspension performance. Since there is no fully stiff material, when the chassi is under some load, it tends to deform, like other components of the car. Thus, the torsional stiffness working with the roll stiffness results in some value of lateral load transfer that varies according to the definition of certain parameters. And, as this paper shows, the results for lateral load transfer are directly related with the distribution of the total mass of the car along the front and rear axles, and also with the roll stiffness of the suspension, which makes sense because the rigidities are being considered in series, and together they hold up the lateral load transfer caused by the position of the center of gravity. So, it is possible to set a range of values for the torsional stiffness considering different values of lateral load transfer in a way that the suspension system can be considered adjustable through different values of roll stiffness
