| 2 For the first reason the Evenkeel torsion bar is out of the picture. He lent us a long report on handling of cars including causes of wandering, oversteering and understeering. The wandering produced by Studebaker's rubber rear shackles might be eliminated by lowering front end of rear springs. (b) car was rear roll rod (c) no front roll rod. The rake must not be overdone or the front of the car will stick before the back. GM are very impressed by the handling of the rear engined Mercedes, and think that if any exhibit 'swing axle' ie articulated half shafts rear suspension all their cars would handle well, do away with need for rear roll rod and lessen considerably damping required from rear shock abs. By gauge of the 120 Packard that with lowish front & rear tire pressures the car handles badly but on letting down the front pressures 6 lbs handles very well. | ||
