Abstract. The paper details the optimum choice of the front suspension of an automobile. The influence of suspension on the steering geometry is studied by considering the various combinations of joints at the four-bar mechanism of the front suspension. The purpose of the suspension is to make the job easier for the tires and give a predictable behavior so that the driver will have control of the car. The most common suspension used is double wishbone. The performance of the steering geometry depends upon the performance of various steering parameters such as kingpin angle, caster angle, camber angle, toe in and out and scrub radius. This steering geometry depends upon the position of kingpin axis an imaginary line passing through the knuckle pin. The steering geometry is a function of vehicle speed, link lengths, and road condition. The selection of the optimum choice of the suspension makes the benefit the comfort for driving and controlling the vehicle conditions.
