Modified Front Suspension Rebound Stops. Phantom III . We are anxious to know as soon as possible if the rebound stops to N.Sch.4957 can be recommended for production. Experiments have shewn that with the chassis being turned out at present the rubber rebound stop does not come into action much before the suspension spring comes on to its stop, after which the rubber has only to carry the weight of the wheel and linkage,which it fails to do. Under these conditions we are unable to spin the wheels after jacking. Our proposal is to use the modified stops in which the present rebound rubber in harder durometer material has been incorporated, but arranged with some solid backing to reduce the rebound by approximately .700" at wheels, and in combination with this to instruct that after the brakes have been fully adjusted up they should be released one click.
