Sorry not the greatest pic but here is my friend's '07 G35 beside my 370Z. I'd have to take the measuring tape to both of them. I really don't have to much grief at all - in fact I'm not worried about dropping it an inch - it probably better than my old 280ZX was.... I don't drag my rear pipes either... on top of that the front lip is abs plastic or something and very forgiving...
Oh and here is a pic with the front lip...
