When I arrive in London on Monday morning, I shall bring with me the 12% stiffer springs as suggested by R.{Sir Henry Royce} We strongly recommend that you concentrate on tests on 107-MG because it is a car which you know so well. As regards trying with the weight of the front axle. There is no reason why the front axle complete with the brakes off 98-NK car should not be fitted temporarily to 107-MG. This would give you the exact comparison of weight but, of course, the brakes would not be able to be operated. It would not be right to simply bolt weight on to the axle, as weight in the centre of the axle would have a very different effect, compared with the extra weight on the wheels. Our experience has shewn that there is a difference in riding in cars even with supposed identical bodies and springs. We therefore think that the first object should be to prove whether the alterations made in fitting the brakes have caused sufficient deterioration in the springs that it could not be sent out to customers. When this is decided, we might still be left with the problem that one car rides better than another which might mean further investigations. Hs.{Lord Ernest Hives - Chair} | ||
