What is interesting is that the KW coilover kit for the mondeo has actually been modified for the Contour by KW.
I talked with an engineer at KW last fall and he said the main reason the coilover kit worked for the Mondeo and not the Contour was the the diameter of the strut and where it connected on the knuckle. He said they machined a set down so that they would slide into the contour knuckles but they have not yet started production on this, perhaps because the demand is too low.
