| - 26 - There are two main reasons for this, one is the fact that it is necessary to keep the front of the car as low as possible for appearance, road holding and visibility from the driver's seat - this can only be done conventionally by having a small clearance between the spring clips and the buffers. The other controlling factor is the life of the front spring. The length of the front spring is fixed by various considerations. The greater its deflection on maximum bump, the higher the stress and the shorter its life. One means of increasing the spring life is to increase the number of plates. This however increases the amount of material in the spring and hence the unsprung wt. The present R-R front springing is a compromise, endeavouring to give comfort on British roads and at the same time relative immunity from spring breakage on the Continent. (d) Tables of riding complaints and probable causes. | Complaint. | Front suspension. | Rear suspension. | |-------------------------------------------------------------------------|-------------------------------------------------------|------------------------------------------------| | Pitching at speeds above 35 m.p.h. | Front shock dampers too weak. Front springs too strong | Rear shock dampers too weak. | | Rear passengers thrown forward off seat backs at high speeds. | As above. | | | Occasional violent throwing in rear. Riding otherwise good. | | Dry or rusty rear springs. Rear springs too strong. | contd. | ||
