Been looking for this info for awhile now and have yet to find an straight forward answer. So I went out to the garage and pulled off a front and a back and measured and this is what I found. Rear rims appear to be a 0 offset rim, 10" wide with 5" from outer lip to inner hub face on back side, which means there is 5" from hub to outer lip on the outside rim face. Front appears to be a 6" wide rim with 5.5" measured from outer lip to inner hub face on backside of rim with only .5" measured from outer lip to hub face from the outside of rim. Making the front rims 5.5 + .5 with a positive offset of 2.5 Has anyone else tried to measure their stock wheel offsets? What did you guys come up with?

There probably is a thread on that somewhere on this site but I haven't looked.
Here is what I did to my stock front wheels: viewtopic.php?f=1&t=17688&hilit=offset

Wow, never would have thought of doing that. Definitely a good idea. I was looking into buying a set of common offset rims and than using wheel spacers to correct the offset.
