| FILES. X6430 15.3.33. STEERING 18-G-IV. This car, the first to be fitted with front axle control, had at the same time Rudge Whitworth wheels and the latest type Dunlop tyres. Road shocks were very bad particularly between 45 and 55 m.p.h., use of the brakes at this speed on a bumpy road resulting in a tentative wobble. The front tyres were found to be considerably eccentric. Changing these for better ones lessened the road shocks which are still however bad. Particulars taken of the car were as follows. Track 57 3/8". Toe in zero. Force on pendulum lever required just to overcome steering box friction, 4 lbs. in the centre of the lock. Hs{Lord Ernest Hives - Chair}/Gry.{Shadwell Grylls} | ||
