SPOHN claims to have changed out the back glass for Lexan.

Lexan tends to break down (craze) from UV exposure, so Plexiglas, with its' greater resistance to UV, may be a better choice. YMMV

Yeah but the stock tank is low. If you put a fuel cell up in the rear body, you're raising the fuel weight higher, raising CG. Also, even though we want to shoot for even front/rear distribution, I suspect moving weight from the center outwards, even to the rear, isn't a net win. It's still a larger goal to keep the weight centered to make the car more-stable, whereas weight at the edges is like a pendulum. I don't know all the factors and how they play out relative to each other, but just things to consider...

On the other hand, Lexan is much, much tougher and more impact-resistant. Something to think about with rocks and hard chunks of rubber flying at the window, and especially something to think about in a wreck.
