am i correct in saying that the stud pattern for a erst is 4 x 100???

and is the offset et 35????????

what way will the wheel go if say, et 40???? when i say this,what i mean is will the wheel come in contact with the arch or shock?????

 

The stud pattern for all 4 stud fords is 4x108mm et35 is about right if you go for et40 this pushes the wheel in towards the strut eg lower the number further the wheel stick out
