If you saw my other windshield post you know I was trying to get my windshield out so I could more easily put the 12 point cage in. Well the windshield broke ( &%^$*#&@!!! ) so now I'm going to have to get a new one. I was thinking about getting a Lexan windshield. But I had a question about it. This thing will see very limited street use. You know... Only the cruise night kind of a thing. So are Lexan windshields street legal? Will a big rock not come through if/when it gets hit with one on the street? I'd like to save the weight by using Lexan but didn't want to do anything illegal or dangerous either. Let me know what you think. Thanks in advance!!

I don't know if they are legal or not, but a rock will not come through it. It won't like wipers.
That is OK about the wipers. I have a 5 1/2 inch cowl that comes all the way to the windshield. I had to take the wipers off for the hood. So I also took out the motor and the rest of it. Anoter 5 pounds gone!!


Will rainex work on Lexan? Or will that scrath it up as well. Not planing on driveing in the rain. But if for some reason I got caught in it some way to clear the windshield would be great...

Lexan IS DOT legal. It'll need to be at least 1/4" thick. IMO (and I've dealt with a lot of plastics back when I was in the sign biz) Glass, while heavier, is much less labor intensive to maintain. You'll spend just about the same amount of money on a pre cut piece of Lexan as you will for a glass windshield. I've dealt with a few Lexan pieces on race cars and airplanes and you have to be really careful of scratching them. A friend of mine used to use Lemon Pledge on his airplane wind screen, still they'll craze and starburst after a few years.

Looking like it is going to be a stock style windshield. When I finally got the old one out it really wasn't as heavy as I thought it would be. Plus I can have the glass guy come out and install it with new trim on the outside for $30 bucks cheaper than just buying and me putting in the Lexan.

....plus I won't have to deal with the windshield scratching up over time and then getting the 'starburst' effect like Lexan does. The weight savings alone plus the difference in cost don't really make it worth it IMHO..

Anybody have any thoughts to the contrary?? I'd really like to not f*ck this decision up.

Lexan's weight per square foot is just about half that of the glass used in Mustangs. Really roughly guestimating, (my Mustang and measuring tape are WAY out side!) I come up with 50 square feet of glass TOTAL! on a hatch back. So approximately 140lbs for the glass and 70 for the lexan. For the windshield alone it's approximately a 15lb difference.

I can get a good used stock windshield for $50 and have it installed for another $50. You don't want a used Lexan window, so you will have to pay new prices, and the stuff isn't cheap as you already know.

I wouldn't do it on a street car myself. Not much gain for the price and hassle.

I just made my own windows

There is a plastic sheeting supplier here in town and I asked him about doin it for my car.

He sold me 2 sheets of 3/16ths lexan with the extra mar-guard coatings for around 275 bucks and I did the whole car. And I still have 1/2 a sheet left.
