Just recently(few days ago), while I was installing my Hartge lip, I had no problem getting into foglight area without lifting the car up. It is actually easier and less hassle to do it without the bolts, as long as you've done it before.
the reason I posted pics are to show you guys clearly where the bolts are. so its not an overkill.
Just look at the pics, see where the bolts are. Without lifting the car, turn the wheels to the opposite direction(so you have more room to play with), reach the bolts with your hands, use the tools and take them off. then you are good to go. Difference between lifting and not lifting is, you can't really see the bolts when you are trying to take them off. so you might want to spare extra few minutes if this is your first time taking those bolts off at the bottom just because you have to "feel" where the bolts are.
Like KL2DC said, only big difference is getting your pants all dirty.
and thats a big deal for me.
