I have read many posts now, but still struggle with one issue.
Help me understand wheel geometry.
I know this is backwards from the correct mounting procedure, but hear me out.
If you were to imagine the wheel spacer already mounted to a newer Ford OEM wheel with 4" of back spacing and now you have only 2" due to adding the spacer, haven't you just changed the geometry on the wheel to be more in line with a wheel made for the vehicle (not using adapters)?
It seems like common sense that you are not really putting your family or rig in jeopardy by using spacers. Unless the spacers have now created a weak point and could shear off under a heavy load.
Personally and I think this has to do with each user on this forum it's all in how you use your X. I have the eBay HUBCENTRIC spacers and love them. They were 1/3 the price and are made just as well. However I have a 2wd and the 5.4 PLUS I don't tow. So I am at the complete opposite end of the spectrum from the better half on here I'm what you call poor (see; eats shoes for dinner) so I buy what I can afford and do the best that I can If I could afford a diesel or a 4wd I would never have gone with the eBay spacers, but then again I wouldn't have been in the same income bracket.
We all have 2 inch spacers if we're running the newer wheels and the OEM wheels sit where the wheels sit now. The spacers just put them back where they are supposed to be. It doesn't change anything at all, just the backspacing.
