I bought a different IKON lip. I took my bumper off to install. It needed lots of shaping and sanding to fit right. The provided holes did not line up at all.
It was also warped. (put it in hot sun, bla, bla... heat gun bla) I did. Then adhesion promoter, primer, more sanding, paint, and clear. It looks ok in the pic, but it always was warped on the driver side. I ended up ripping it off. Meh, you get what you pay for.
