R-R SUSPENSION. x832 x8410 With reference to CWBA/GMK3.4.26. We do not think it would be worth while obtaining a set of the device you mention because we can see exactly how they are likely to improve the riding of the car and the resultant disadvantages incurred. With regard to the advantages of this device when using springs stiffer at the centre. We realise the advantages of having springs the maximum permissible length at the rear of the front axle for riding comfort and resistance to brake torque. At the moment, lengthening the rear of the front springs is again under consideration but it does not appear that much will be able to be done in this direction.
