I'd venture a guess that the likelihood of a rock poking in the small gap between the bumper and gas tank skid is probably pretty low. I see what you mean and am surprised to see the difference, but it'd have to be a pretty unluckily angled extremely pointy rock to be an issue, wouldn't it? I'm no expert but I'd think you'd be hitting either the corner of the bumper, or the GTS?
I looked at mine and don’t have a single scratch across the uncovered by bumper area. The bumper mount spots with the bolts underneath the frame are scratched to hell.
The tow points are scratched. Both sides of my savvy gts are slightly dented and there are scratches all the way across the gts.
I’m sure I’ll get a rock in there at some point but hasn’t happened yet.
