sounds like a nice build! if ur guna be doing such a nice job like it sounds ur doing id put some 33s on it. the i6 will work fine with 33s. my stock i6 works great with my 35s but i did have to regear. so if ur guna end up regear or putting lockers in then 33s would be a nice way to go if not 31s with 1-2" of lift will work.
