On one website they provide the math on thickness and cold bends. The thinner, the more you can bend it. Not sure if it was for polycarbonate or acrylic though, will have to Google it again, too many bookmarks at this point.
I bet 1/8" would cold bend, but you would need support spars to keep it from blowing out at speed.
I think snbush67 is correct about needing to apply heat, but the vette guy said he did his cold, so I'm fairly confused at this point.
I've used either 1/4" or 3/16" smoked acrylic on my hovercraft, the windscreen bend I played with was 18"-20" radius and that seemed to max it out without stressing it too much. The Targa glass is nearly 90 degrees at the hoop, similar to the vette though.
I just don't understand why I can find dozens of pictures of rear plastic windows on 911 coupes, and not a single Targa.
The Cabriolets and Targas can be found with fiberglass hard shell caps, that seems to have filled the track market.
