scraped laterally along the concrete barrier, broke one tab on the bumper cover.

frame looks straight, nothing is misaligned in the front end, I had already removed all of the plastic screws so it popped out without damage.
it doesn't pull in one direction or vibrate etc, but the front brakes started squealing after about half an hour of driving, once I dropped to a lower speed (< 40mph), looks like they were rubbing. Rotors were VERY hot when I pulled over, outer edge of the rotor is worn smooth instead of slightly rough like it used to be.
eventually I decided to just drive on them, then the squealing stopped after about a mile. No more noise now. Should I be worried?
EDIT: the fender liners are zip-tied to the frame to keep them from scraping on the ground, just realized that they look a lil weird in that picture

 

I'd pull the wheels and inspect the brakes just to be sure. Check the backing plate to be sure it isn't bent and that "something" didn't get stuck in there (small rock, ect).

 

Bumper is fixed now, ultra JDM :/

I took a look at the brakes, nothing misaligned or bent, but I'm keeping an eye out.
