Hello
I need to measure the offset of the wheels below

http://s148.photobucket.com/albums/s30/kastratocliosport/spares%20MK%20indy%20racing/?action=view&current=IMG_0973.jpg

Can somebody post a drawing indicating how to measure offset?
Does anybody knows the correct sierra offset? (need to fit them on a MK Indy)
Does anybody knows the offset of these wheels?(I know that they came off a ford, I think escort.)
Thanks in advance

Hi George,

Have a read/look at this...

I think that the offset for RWD Escort is 15-18 (or something like that) and the offset for Sierra is 32 (I'm going from memory when I bought my wheels and it was a while ago, so if I'm wrong hopefully someone will correct me!)

The higher the et the nearer the centre is to the front of the rim
