Hi guys , I am getting ready to purchase some new wheels for my rig . I want to go a little wider from 7'' to 8'' in order to get a better balance with these stuper swampers and also to push out the back spacing a little for a wider stance . I was wondering what you fine fellas would recommend for back spacing ? I dont want the wheels sticking out so far that it looks silly but enough to make side hilling a little more stable . if you have pics or your new wheels with more back spacing id love to see the pics. Im trying to find some nice light aluminum wheels on craigslist but Im not having much luck so I think im going to end up with some 15x8 black steel rock crawler type wheels . Thanks for any and all input
