This is supported by the fact that whenever we have increased the tendency to wobble we have increased the road shocks felt on the steering wheel. When we fitted front wheel brakes to the 40/50 we did not alter the steering, but there is no doubt that the shocks on the steering were increased. If we fit low pressure tyres, shocks on the steering wheel are increased. As you will see in other reports, we consider now that mechanically, hydraulic shock absorbers are quite satisfactory. The amount of running on the bump is three or four times greater than the best of other makers we have tried. During the whole of the test their efficiency was measured after every 2 hrs. bumping and it was not found to vary any appreciable amount. This is a very different result to that which we obtained with the Houdaille or the Berkshire. The results of all our recent tests still confirm that with the new axle which is slightly more off centre-point and lighter, will be an improvement.
