Hoping someone can shed some light on how this man widened these rims with the centerpice being one solid piece all the way from the center hole to the outer rim edge. That one piece is welded to the remaining part of the rim. From what i can see , you would need to cut out the star and painted web portion to achieve desired depth of 7"to accommodate a 4" ring. The beauty rings appear to be 4" to me ,i could be wrong but they do appear deeper than the photo of the mock up Ed posted. I want to do this with my car , any help is very much appreciated.
