Hello BlueDevil63: I saw your messages of your rear wheel and tire setup but did not see if you have mods and the tire poke out if any or if the tire is flush or has room on the outside. My apologies if I missed those posts. I have a Boss '13, Watts link, coil overs but stock height, will shave the bump stop bracket. I would like to run 20x12 rears with Michelin PSS 325/25/20. Could you please, share your some more rear specifications: any room left inward?; is the tire flush?/how much the outer side pokes out if any?/how much the outer side is inward if any?; any mods for the rear wheel well or suspension?; spacers? Any rubbing? Thank you for your time!
