This master’s thesis presents the design and analytical development of an anti-roll system for a GT3-class racing vehicle, conducted in collaboration with Podium Advanced Technologies within an official FIA homologation program. The work combines vehicle dynamics, structural design, and computational optimization to define a suspension subsystem capable of meeting the performance, durability, and regulatory constraints of GT3 endurance competition. The project’s objective is to conceive, model, and validate a passive mechanical anti-roll mechanism that ensures compliant roll stiffness, structural integrity, and adjustability within the packaging limitations of a high-performance racing chassis. The study begins with an overview of the FIA GT3 framework, where Balance of Performance regulations and endurance reliability requirements govern system design.
