This column is for Name of Person addressed. DATE. The smallest ground clearance of the chassis is actually the silencer which under the first condition is only 6.9" and the others vary accordingly. The above records are taken under the assumption that the car under normal load gives flat camber springs, but our actual tests as regards springing of cars is that the springs are as weak as possible but will just carry the maximum load. With this springing we ensure that the weakest possible springs are fitted to the car which is the object we are trying to arrive at with our springing, hence we do not definitely work to normal load conditions, as otherwise it is possible that the car may be undersprung for maximum load. With our maximum load it is possible for the springs to have ¾" negative camber which is the maximum allowance. Under these Contd. This sheet must be filed with the correspondence to which it refers. | ||
