FAL formed windows suck. When my car got broken into, instead of replacing the one broken window. I replaced the hatch and both rear quarters with the FAL formed Flexite windows. And it was a big waist of 400 bucks. The painted surface behind the windows is starting to separate from the back of the windows. So now I have fucking air bubbles behind the windows. Looks like shit . I didn't weigh the quarter glass. But I did weigh the factory hatch glass on a bathroom scale. And the factory glass weighed 20 pounds and the FAL weighed 10 pounds. So even if I saved 5 pounds on both quarters. That's a total of 20 pounds saved. Definitely not worth 400 bucks.
