It's much safer to do this spring mod and then leave them flipped back if you have no rear passengers. If someone does ride in the back, just flip the headrest up for the time and then all you need to do is drop the seatback forward halfway and push the headrest back again, and then lock the seatback upright again.
You didn't mention if you have a 2 door or 4. I have a '12 2 door. If you look around the plastic "collar" where the headrest shafts go through you will see that there is a small tab you can depress which will allow you to pull the headrest out.
Visibility is definitely better with the headrests out of the way. Especially the one on the passenger side. I'm thinking of picking up a couple of bungee cords for just this reason. I drove a few days with the seats folded down but decided that the seat belt buckles pressing into the leather probably wasn't going to do it any favours in the long run.
