| contd :- -2- The weak steering tube springs were actually fitted as standard on the very first Phantom chassis, but owing to the tendency for low speed wobbles and also to the complaints of stiff steerings which did not allow us to fix any further friction in the pivots to overcome the wobbles, and as the road shocks were no worse than the Silver Ghost with 4-wheel brakes, the weak springs were replaced by the stronger ones which were standard on the Silver Ghost for many years. We think it is probable that when we fit the weaker springs in the side steering tube, increased friction will be necessary to prevent low speed wobbles. Hs. {Lord Ernest Hives - Chair} | ||
