| contd :- -2- FRONT SPRINGS - 40/50 HP. We consider that the front springs should be arranged to have the same 50% increase of static load to the buffer as the rear springs. This means that front springs should be 15% stronger than for British conditions which will make the normal camber flat, so raising the front of the car .500". This, with the alteration to the rear springs, will keep the car on an even keel. British conditions 1000 lbs. spring. Australia " 1150 " We suggest that if this springing satisfies Pt. the 20 HP. car should be dealt with in a similar manner. The present front springs for Australia arranged to give a loaded camber of .25" negative give a static load to bring the axle to the buffer 28% above std. springs, the proposal 15% stronger spring increases this to 56% above the standard spring.
