It seems to be agreed by everybody that eventually the B.50 frame will have to be used for replacing Wraith. This means that the rear axles, rear road springs and transmission will have to be adequate for dealing with a car of this weight. Also, the axle top gear ratio will have to be as low as 4.8 if the car is to have an overdrive. It is suggested that special long rear road springs should be fitted for these heavy bodies, so that the smaller car, such as B.III, will not be penalised by having to carry heavy road springs. We should like a summary preparing as to how we are going to cater for these heavy bodies. Rm.{William Robotham - Chief Engineer} | ||
