DIY Rear lip

[victorhasheart]

I just recently read a post on how to install a front lip. I was hoping i could do the same for the rear, but the problem is is that the back bumper doesn't curve in like the front, therefore there is nothing to attach the lip too. I really want to do this, so if there is anyway someone could help me be innovative and find a way to install a lip in the back like what was done in the front, it would mean a lot to me! Thanks!
