Your best bet is to get a 2D or 4D front lip from them ($60 for ABS plastic, or $90 for the polyurethane), then mod it to fit the lower center air dam. All you really need to do is shave off a few inches on either side of the center portion of the lip, and you're good to go. I'm not sure if there's a lot of modification to get a 4D lip to fit the coupe bumper though, its possible it may be a little short on each side of the bumper.
Polyurethane is definitely much more flexible. I have an ABS lip and I've scraped it on numerous bumps and driveways, but its held up okay. Then again, its not like I aim for potholes or approach a driveway straight on lol. Go with the polyurethane, and have it professionally painted.
