Being that the glass would be considerable thinner would you be able to see visibly much of a difference? Also will the windows allow more air into the cab, I wouldn't think it would but it may not press as firmly. Thanks for any help.

 

No idea what your talking about but nice M4. Yours?

 

where would you be using this?

properly sealed it wont let any air in just like your windows, and 1/8 inch is too thin, it would flex too much used as and window, from air forces and vigration, causeing it to crack and just fall apart, not to mention the thunder like noise.

you could reinforce it to hold up and not flex but this would hinder your visibility greatly

 

lexan is a plastic, not glass. If your using it like glass, then you need to router the edges(for best fitment). What are you using it for?

 

Unless its a race only car lexan in a street car is pointless and will drive you nuts.
