X.507 X.5005 X.235 X.7005 I feel sure that the best we can do, until we can alter the weight distribution, is : (1) To fit the most flexible and frictionless springs possible, without badly bumping on the rubbers, (2) and to fit ample shock dampers - our hydraulic as they are less objectionable than solid friction Hartford and internal friction of springs. I fear we are carrying both these far enough, because both 10-G-4 and EAC.7. (now that the latter has been increased in damping) are the best riding cars we have had The risk of bumping, and seasickness, is much reduced by increasing (2). This is the same old suggestion but we cannot get it done, therefore try to overdo it. TORQUE REACTIONS, OVERRUNNING VIBRATIONS. These are definitely reduced by rubber suspension at rear, plus front engine dampers very tight. R.{Sir Henry Royce} | ||
