Desert dog;

I used 2" spacers in the rears and 1.5" in the front to mount the later wheels on my Suburban.
I don't recall if the spacers come with the metric lugs or not.

I did go back to steel wheels.

The spacers will work if you just want to mount them for rollers. (great idea)

Hope that helps some and subscribed for the photos, Good Luck!
