| IV (F) The damping used on the front of the Cadillac is about 60 lbs at the wheel with a certain amount of pressure velocity effect superposed i.e. Graph: Y-axis: 50 LBS, LOAD X-axis: OIL VEL (G) In all the lever schemes, whether Dubonnet, Leon Laisne or others, there is a tendency for the car to either resist or exaggerate the normal tendency to dip when the brake torque is applied to the wheels. Oy has made a study of this a copy of which I [strikethrough] will let you have later. (H) Independent Rear Suspension Do Cadillacs have three cars running about fitted with a scheme which consists of radius arms running backwards about 20". | ||
