| 50U, 25 RUE GIDE, LEVALLOIS-PERRET. PARIS. FRANCE. To. Rm.{William Robotham - Chief Engineer} ~~Mr G.W.H.~~ 22. G.{Mr Griffiths - Chief Accountant / Mr Gnapp} V.{VIENNA} SUSPENSION We have been out for a final run with Sr. Trial's car, which is fitted with intermediate rating springs and an initial damper setting of 70 lbs in the front, and 70 lbs at the rear, against our present suspension using a front roll-bar and an initial damping of 40 lbs all round. The general opinion we have gathered is, that 22.G.V. is far and away the better car as far as controlability is concerned. Cornering, braking, and steering, is superior in every case, which from a driver's point of view is absolutely necessary under French conditions. We do however agree with Sr. that the back seat ride is not so good, and seems rather too hard for constant town work. But we are of the opinion that his trial's car which has much softer rear seats and a close-coupled body has a considerable advantage over ours in this respect, and that these facts are largely responsible for the increased rear seat comfort on his car. He is of the opinion that although controlability is of utmost importance in France, it would be preferable to sacrifice a degree of controlability and if by doing so, obtain a smoother rear seat ride. We are therefore softening our dampers to try and obtain a better compromise between controlability and rear seat ride, and will then compare our results with the car fitted with the dampers which Leslie has forwarded us.
