Coilovers may well do but they are adjustable, but the normal spring ratings are different due to the extra weight, and in the ST's case the springs will be different as it has a lower ride height!

Not sure if the gearbox mounting points are different, probably though as the 2L has a different gearbox (MTX 75)

Yes the Focus also has selector cables so they should be interchangeable in theory.

As I say if you do a search on here there is a thread where everything is listed that needs doing.
