i've read on this site that lowering springs will wear out stock struts quickly, especially older ones...i am not positive about this but the st200 struts are stock (on mondeo) so wouldn't the lowering springs also cause these to wear (prematurely)?

the best bet im my opinion would be to get the eibach's and koni adjustables or some other aftermarket strut that can handle lowering springs
