| CJ1/E17/7/22 - 2 - Further fuller particulars of the above alterations are given in H's memo. to BY, R2/M15/7/22. It was decided that Dunlop wire wheels with straight sided cord tyres should be made standard: Further, that the bracket to carry spare wheels should be fixed as standard on the back of the chassis: Also, lamp brackets front stays should be made standard. The luggage carrier and a carrier for spare wheel at the side of the car should be charged as extras. The Design Office will send to Sales the design for carrying luggage in addition to spare wheel at the back of the car. CJ drew attention to the fact that the vibration of on the high compression chassis was excessive and that there was a tendency in the Company to go 'all out' for power and speed and that, in doing so, we were sacrificing the silkiness, silence and absence of vibration which had made the reputation of the Rolls-Royce car. Hs.{Lord Ernest Hives - Chair} undertook to ascertain why the Riviera Trials car had apparently high compression but the vibration had largely been eliminated. Until the Works could guarantee that they could deliver high compression chassis without excessive vibration, it was agreed that no further high compression chassis should be made or delivered to the public. The Design Department were requested to study the question as to a spare supply of petrol after the main tank of petrol had been run dry, or the provision of a petrol indicator. The Sales Conference was requested to consider the question as to why we should not make standard Dunlop straight sided tyres on the 40/50 chassis. CJ. | ||
