This is bizzare to me. There are thousands of pro touring cars running 19'' and 20'' wheels and many of them have installed bolt-in rear 4 link kits, which means they haven't altered the arch of their frame rails. Those cars are prowling the streets with lowered ride heights as I have mocked up on my car. I have 1'' clearance from the top of the rear axle housing to the rubber bump stop. Unless I am dealing with faulty eye sight or something far bigger than my brain can fathom... those guys must be bangin' their frames and rear ends together after filling their gas tanks, and bellies with lunch in some cases!

Can anyone explain this strange phenomenon to me before I break out the plasma cutter or perhaps lose my mind?!
