That looks very normal as far as setup goes. I would be surprised if you got any rubbing. 20mm offset is common, and you're running the stock size. Yes the AD08 run a tad wide, but that usually only matters on sizes that are more aggressive (like 255/35R19 up front). The KW max lowering is about 1.5", which is not crazy, and the lower offset keeps there from being much worry about clearance on the suspension. There are no guarantees in life, but I can't see you having any real problem.
