Bump Steer And Steering Shimming

Just removed my rack to regrease, change seals and fit poly bushes. In the process looked at the shims on the chassis used to adjust the bump steer (as I want to check the bump steer afterwards) and was wondering If someone could answer me the following:-
1) Why are they fitted?
2) Are the chassis not made up on a jig to a high accuracy?
3) How are the shim dimensions arrived at by Lotus? ie what datum points are used to produce the correct shim heights?
4) Any further info on this topic. on which I am not so well versed much appreciated.
thanks
