I love that wheel setup and no rubbing issues at all just in hard bumps... nothing to worry about. Also you have to adjust the camber to make it work but the same nothing to worry about. Here are some pics of my Z with that wheel setup

I hope that can help you in something haha! if you have a question of my 19"wheels setup let me know!
