my goal is accurately (but safely) recreate the look below. Currently the 7" slots with the g50 tires don't "stickout" past the fender lip (like below), but they do come into contact with it.
Man, that is a really cool look you're after. I love it. But you need to understand most states now have laws regarding tires that protrude past fenders. And rightly so. I would hate to be driving my nice $100,000 Mercedes behind you when you pick up a rock and smash my windshield. (Not that I have any Mercedes) but you get the idea. You can come close to that look and keep the tires under the fenders where they need to be.
