I have a large crack and I like to "upgrade" when things break.
Clearone has a kit that you have to cut yourself...I'd rather not. Also, does 1/8" vs 3/16" really matter? Both should be plenty strong - so lighter I would think is better.
But you might want to check with local laws as some areas Lexan is not legal for your front windshield. Great weight saver bit it scratches very easily and discolors over time.
Lexan windows won't pass any state inspection I'll bet. Side, rear or front, unless the DOT approval is molded into them.
( I've never done anything that might be even somewhat illegal. I just couldn't find the mufflers that were in the sidepipes when I needed them so I just put the pipes back on without them).
I'm wondering if the state inspection guys would know or care...also, how does this law apply to 41 yr-old cars? Anywho, I'd love to take out my glasspacks, but I once had a cop threaten me about them as it is...
I worked for GE plastics in a previous life and there are various "hard coat" laminated versions of Lexan, but none are as hard as glass. I would expect that a plastic windshield would scratch in short order if the wipers get used. I also suspect a Lexan shield would be more expensive than a glass one... the stuff's not cheap by any means!

If you go with SpeedGlass, even tho it's got a scratch resistant coating I'd seriously consider tear offs, especially for road racing. Windshields, windscreens, visors and paint can take a serious beating out there.

They're similar to visor tear offs, except you apply them more like a widow tint that goes on the exterior. Whether or not you think it's worth the additional investment is up to you, but it's surely much easier to strip and replace. A couple of links that may help...
We ran a stock car out at Southside Speedway back in the '80's. I purchased a sheet of Lexan from Cadillac Plastics and cut and fit it.
There wasn't much to it.
I hear you there! For some reason I thought the OP said something about saving money. My mistake. I still recommend against it though. Too easy to scratch. You'd see scratches just from washing the car. Not worth it on a street car.
I have a lexan windshield in my C3 since 4 years, it indeed needs some extra care for cleaning and you can't use your wipers but the weight saving was enough pro for me for the change.

The issue of practicality isn't necessarily black & white for all of us, as while this may not make sense for a DD it certainly does so for a racing/track-day car. A good many enthusiasts happen to fall somewhere in between; the nearer to the racing end one resides the more sensible are any such hardcore mods. That said, not everyone defines performance solely by 1/4 mi ET's (nothing against drag racing, BTDT), and simply adding more power doesn't help in corners or under braking.
Also, we're not exactly talking about using something off the shelf from the big box store down the street here. Besides, every light aircraft in which I've ever flown has had plastic windscreens/windows of one sort or another, and IMOE as long as you don't fly thru a flock of large fowl they can last a good many years with proper care. Admittedly, this care is critical, so do keep Bubba a distance away from it.
