I called Wheel Adaptors USA and spoke with Jeff and explained my issue with my 35"X12.5" Nitto Ridge Grapplers Rubbing on the front Sway Bars, I told him I was thinking of using a 1/2" wheel adaptor to clear it. Jeff right away recommended the 1-1/4" wheel adaptor to eliminate any trimming of the existing lugs because that was a huge concern for me if I wanted to later go with a wider wheel. Turned out the young man was a Genius, it gave me a nice Poke not to aggressive but totally new stance. I'm very pleased and will refer Jeff and Wheel Adaptors USA to the Huge $ Wheel Drive community here in Las Vegas Nevada
