As the vehicle becomes increasingly high performance, it may happen that the wheel nuts are loosen or the wheel bolts are broken during the endurance test. This paper examined the variation in the bolt clamping force and the bolt teeth stress in relation to the clamping conditions of the wheel nuts.

Coupled Torsion Beam Axle (CTBA) type rear suspension is being widely used in automotive industry because of its low cost, however, this type of suspension is liable for moan noise frequently. In this paper, through the investigation on the moan improvement cases and experimental analysis including TPA and EMA, we propose a design modification of CTBA to prevent the outbreak of moan noise. The proposal was validated through the dynamic stiffness analysis of caliper attachment point numerically.

Handling characteristics such as maximum lateral acceleration, understeer gradient, and yaw rate response are very important for high performance car which is driven not only on the public road, but also on the track. In this paper, it is verified that vehicle specifications and suspension design including geometry, lateral stiffness, and unsprung mass reduction are important considerations for High Performance Vehicle"s handling characteristics.
