The 10% stronger springs were, in our opinion, the best compromise for a speed car. We are sure, when we come to EAC.11. speed models, a car which will do over 80 m.p.h., we shall never keep it on the road with the flexible springs which are required to give the comfort which Sales Dept. demand at low speeds. 98-NK car which was objected to by Sales with regard to springing was the car which had been run by them in April with the same springs without criticism. The springs on that car were to our specification. There was one instance when we thought we had fitted the wrong springs to a car submitted to Sales. Because we were not absolutely sure, we sent other springs to replace them. It was proved however that the original front springs were correct. This was confirmed by the fact that Sales KEK found no difference in the riding of the car after the new springs had been fitted. The delay in this case was 12 hours. As a principle we adopt the attitude, when there is the least doubt that we are wrong, and check the job again. Hs.{Lord Ernest Hives - Chair} | ||
