I think you can run stock offset which is 3+2 if im not mistaken. I am running 4+1 because I have heard they handle better. I am also running the DC-4 aarms, I am still on my stock rims and tires, but have ultimates, with 4+1 on the way. I think you will be right near 48 or 49 inches with stocks...I think that is what I heard other guys saying here. Hope this helps.
