We have a number of new parts which we want to try on the car as soon as possible and we want to avoid the prolonged delay which occurred when we sent the last shock absorber out to you. We were very interested in your report on Suspension and the information you are obtaining by altering the shock absorber loads. We should like you to confirm all your results as far as possible and especially to notice the behaviour of the car at 20 to 30 m.p.h. on a typical main road surface, wavy, but without potholes.
