| contd :- -4- (2) If ever obstinate cases of high speed wobbles arise, it is of no use to attempt to eliminate them by increasing the front damper loading unless the rear of the car is also suitably damped. Open cars are also more likely to be persistent wobblers than closed cars because heavy car bodies necessitate strong springs and the whole rear of the chassis is restrained from moving torsionally on the springs. Unless the rear of the car is well damped, a stiff frame torsionally is not of much use. In any case the period- icity of normal types of frames is not in the region of high speed wobble frequency. We conceive that a stiff frame and stiff rear springs well damped would make the front dampers do the maximum amount of work, so preventing a high speed wobble from starting.
