| X.990 Extract from Hs{Lord Ernest Hives - Chair}4/LG20.2.20. X.963 RE STEERING ON 2.EX. -------------------------- We came to the conclusion that the effect on the in steering must be some way have been caused by the centre point steering. To prove this we fitted Michelin Disc wheels and hubs on the front of 49-GB car. On this car, however, we can find no disadvantage arising from the centre point steering. We later on fitted Michelin disc wheels at the rear and shot these with X.3926. Goodyear rubber non-skid tyres. This meant then that the car was identical to 2.EX both as regard steering, springing, and tyres. With this combination we found that we got a similar complaint perhaps in a less degree, to that which we had on .2EX. The complaint we found is that going along a straight road it is very difficult ti keep the car straight especially if the steering is held tightly. We have proved that this complaint is greatly exaggerated when Goodyear rubber non-skid covers is are on the back wheels. If the standard Dunlop tyres are used. X.990. when one knows the complaint is there, one can still pick it out but it is nothing like so obvious. We have heard from the driver of 2.EX Car in France that after he had changed one of the Goodyear for a steel studded tyre the steering of the car was different and quite satisfactory. We have also had another report from Mr. Parsons at Paris who was with Mr. Salamanca during some of his early Contd. | ||
