| X235 CWB21/DN5.3.26. TO CJ c. to BJ FROM CWB Hydraulic Shock-Absorbers. Reference Hs {Lord Ernest Hives - Chair} 7/LC3.3.26, I consider we should obtain some further information from Hs {Lord Ernest Hives - Chair} regarding the effect of fitting lower pressure tyres as regards the shocks on the steering-wheel. In this report he states that there is a direct connection between shocks felt on the steering-wheel and wobbles. At the same time we know that the hydraulic shock-absorbers will practically eliminate the tendency to wheel wobble, even with the lower pressure tyres, - presumably, therefore, will also make the shocks on the steering-wheel normal again. I consider this is most important, as if success in eliminating shocks is attained on these lines, it will enable us to retain our present type high gear steering, which has many advantages, in fact, possesses only the disadvantage that the shocks at high speed are very severe indeed and the controllability of the car under these circumstances is uncertain.
