| ROAD SPRINGS. Written by Mr Royce on March 5th 1912. Handed to T.C. on March 8th. Mr Royce said - It may be possible to work with less spring movement owing to the increase in length of the springs and the decrease in the camber. Experiments should be made with a total initial set of 3" in the front spring and an initial set of 3" in the half spring (rear) and 1 1/2" in the quarter rear spring. These experiments should be made with flat and negative camber springs. X910 | ||
