I can certainly see the appeal on hellaflush cars; especially the ones done right. That is, the wheels and tires are actually flushed with the fenders--not poking out with a ridiculous amount of negative camber. Controlled negative camber in the front actually provides more grip during corner exits as the wheels tend to "straighten" during cornering, but I'm pretty sure the hellaflush crowd don't really care about that nonsense
