I've also had my bumper smacked off, first a small crack, and then it turned into the entire corner.
These are incredibly flimsy, no amount of good driving is going to get around poorly designed driveways and neglected pot holes.
Also, my bumper cost about 500, with parts, labor, and paint.
It took me about 1 week to not scrape the bumper again.....in the same F*&^%& place.
It really wasn't that bad though, just a little on the bottom.
Anyone have a good lift suggestion? Spacers? An 1" maybe? Or more?
