I installed my lip yesterday, honestly the lip was such a pain to get on. I let it sit in the sun for 3 hours but even that didn't help. I screwed the two sides down first, and then worked my way to the middle of the lip with alternating sides.

My lip was so bent that the bumper actually doesn't fit like it used to due to the lip's shape not conforming to the bumper (I took my bumper off to install the lip). Another thing to note is the fender lining doesn't line up with the holes you drill to attach the lip inside of the fender.

You really get what you pay for with this thing....
