the kits could be made to fit. you'll probably have to shave off an inch or so of the "under bumber" (that egg crate looking piece under the cosmetci covers) the european bumpers are shallower than ours.
in the rear, you'd probably have to do the same, and modify your trunk lid to fit. their trunks (or boots) are flush with the sheet metal, ours bump down about an inch to make the stats seem like the lift to the trunk was lower than a competitor.
