[QUOTE="timetraveller, post: 104011, member: 456"] OK Chaps, always one to learn from others and so thanks for the help and advice. However, I suspect that with a long spring like the front suspension ones, as opposed, say to a valve spring the difference will not be very great. In the search for accuracy I have just counted the number of coils in one of the 36 lbs/inch springs and there are 52. Removing three from this figure as advised above to take into account the flattened end coils gives 49. Half an inch of shortening means removing about three coils so using the above calculation means that (49/46) x 36 gives 38.3 lbs/inch. My crude calculation gave 37.125. Near enough I would have thought. [/QUOTE]
