Clois Harlan Which One??? Track the lexan would be safer. Not sure if they would let you drive on the street with a lexan and a couple of plastic covers to keep the scratches out of it. It's just like Nascar, 500 miles and throw it in the garbage. The wieght different is only a couple of pounds. Both will crack under high vibrations from the car. The question is do you like glass splinters or plastic??? Rick L.
