ne of the reasons why devotes so much time to suspension and steering issues is their immense influence on how your car is designed to behave, both on test tracks and public roads. Motor manufacturers devote considerable efforts to design a car with ride and handling that is vice-free but comfortable yet responsive. The steering must not be twitchy at speed, but it has to be geared sensibly forVibration and Harshness (NVH) as it is known in the trade. Part of this includes optimising positive primary and secondary ride characteristics, although it is surprising how many of today’s manufacturers do not match their vehicle’s suspension settings with those of the seats. Additionally, road noise that is transmitted through the tyres must also be considered by the suspension, as well as interior/exterior sound-deadening material.
