CCIE, my yellow car and the red roadster have over 10,000 miles each on them. I have never installed air bags or a lift system.
I made up a heavy duty front spoiler bar that is a great place to jack up the car too.
In both cases it extends below the fiberglass by about 1/4". The steel is the first thing to hit the ground and protects the fiberglass in every case.
My thinking behind this was, a pothole or unexpected bump at night will damage the fiberglass if you don't protect it. I will bet that most people will forget to use the lift or
say, "dang I should have used the lift on that one".
I don't have roller wheels up front but you can do it.
I prefer to drag the steel bar across the asphalt and come out unscathed on the other side to an audience in amazement.
AND IT'S WAY CHEAPER!!!
