X3900 X8440 7877-4 We have swung a Phantom sports car. We find that k²/AB for this car is .43. This sports car is agreed by everyone to be the best sprung car they have tried. No matter what springs we put on the car, it seems to ride wonderfully well. This is the first Phantom car we have swung. We give you the figures because we think they may interest you. Naturally, we shall do a number of tests to see if we can find out why there is this departure from the k²/AB theory and whether, other things being equal, a low e centre of gravity does inherently give one good riding qualities. We will let you have any further information as soon as it comes to hand, and perhaps you could think of some tests you would like us to do when you have seen these figures. We are sending you a photograph of the Sports Car balanced at an angle of 54° on the wheel rims. Its road holding qualities are certainly abnormally good and you will note that the centre of gravity is some 5" below the top of the tyres.
