We have now an epidemic of weak springing on both 25 HP. and Phantom II. Although I agree that Coachbuilders are exceeding their estimated weights (they invariably do) I am convinced we are sailing much too near the wind when we spring chassis at Works for the Continent. I notice that most chassis settle down appreciably after the first 1000 kms. and I strongly recommend the fitting of at least 100 lbs. stronger springs to rear and 50 lbs. in front over and above what you would do for England when you build the chassis. I also am of the opinion that we should stock up to 1200 lbs. springs for rear of 25 Hp. chassis, never fit less than 700 lbs. in front and then only on instances of very light bodies, and for the Phantom II. stock up to 1600 lbs. for rear and 1400 lbs. front. I must say that your desire to give the customer good springing is landing the Company with considerable expense, because customers insist upon our changing the springs free of cost at that. The Speed of our chassis and occasional caneveaux calls for stronger springs. (Sgd). Ps. | ||
