| Steering Shocks I have read with interest By's suggestion. I think we are all too inclined to forget that experiment where we killed a full blooded high speed wobble by pouring water on one tyre. i.e. The gyroscopic torque cannot even keep a wobble that has been started going without reaction between the tyre and the ground. Olley says that, within the limits where he works, the gyroscopic Couples of the wheel have not worried him with regard to steering shocks, and even slight imperfections in geometry have not caused trouble. The thing that has produced a kicking steering every time has been periodic frame movement. The angular movement of the wheel is very little 1" either side of the normal ride position. I cannot say that on any of the wishbone cars that I have tried has the steering kicked appreciably, whilst they all self centre nicely. However they are all at least 20-1 ratio so it is | ||
