The thesis addressed the development of a new rear suspension design for a first-generation Ford Mustang. The original rigid rear axle with leaf springs was used as the starting point, with particular attention paid to high unsprung mass, limited geometry adjustment, axle wrap and wheel hop. A new independent rear suspension was developed with a fixed Ford 9-inch differential, separate driveshafts with constant-velocity joints, adjustable control arms and coilover spring-damper units. The main aluminium components were designed for five-axis CNC milling from EN AW-7075 alloy. Using the textbook Dinamika vozil, basic analytical calculations were carried out for drivetrain loads, vertical loads, longitudinal load transfer during acceleration, the force in the coilover unit and a hand calculation of internal forces, bending moment and reference normal stress in a simplified model of the lower X-shaped control arm. The developed design provides a basis for manufacturing a functional prototype and for subsequent practical validation after all components have been completed.
