Yeah it may be to do with the offset, different ford wheels sometimes have slightly different offset due to what car they are designed for.
Spacers are your answer, nothing too big, 2-3mm should cure it.
To get an idea of what size spacers you need if you don't have immediate access to some, just get some thin washers and place them over the studs until it cures the problem then measure how thick the washers are in total. But also, make sure its not so thick that it rubs on the outer arches when going over bumps.
Also, don't drive mega far with washers behind the wheel, its not suitable.
ORRRRRRRRRR. Just don't go full lock
