Where did you get your lexan? It's an odd size in sheet stock, what thickness?

Thanks

I got mine from MSC Direct, a friend had a work account on there, which gave discounted prices and free shipping on anything, so I got a 4x8 sheet of 3/32" to my door for like $68. You might be able to find it on mcmaster, or if you can find a plastics company local to you.

I think 3/32" is about the right thickness - any less and it will be a bit flimsy, any more and it'll be difficult to bend it to contour to the window opening without using heat, at least with the fiberglass top that I had.

Here's a pic from right after I finished building the racecar last year, before it underwent a season of trying to avoid panel-crushing out-of-class spec miatas... so clean at this point!!

The first place I would start is the rulebook of your favorite sanctioning body.

I know most deal with replacing the windshield and/or side windows, but it would be a good idea to see if the rear window is covered.

I think I used 3/32" also. I just googled "lexington ky plastic supply" and found a place in town that had it in stock. They even cut it to size so that I wasn't paying for more than I needed. I'm not sure how many other locations they have, but General Rubber and Plastics is the name of the place.

I used 1/4". It is over kill, but easy to use still. 3/32" sounds like a winner.

I used 1/8"

Good info, thanks for the posts. Mcmaster has been killing me with shipping, will have to investigate other sources

I pick up from a place called Piedmont Plastics on the north side of Charlotte, NC. They supply quite a few of the NASCAR teams.

We use .187" front and .125" rear. Hard coated polycarbonate that can be washed like normal glass

Can you make two rear windows from one 4x8 sheet? I have a friend that's willing to split to cost with me if we can both use it.

1/8" on the rear works fine. It moves around a bit at high speed but it's not an issue. Doesn't need to withstand any impacts.

Is it possible to glue the front lexan windshield in place like a factory glass windshield. I sure would hate to drill holes in my windshield frame.

speedengineer

yes. I had a 4x8 sheet, which I cut an s2000 rear window out of, as well as a spare s2000 window. I then cut the spare s2000 window down to size for my miata. So it shouldn't be an issue getting two miata windows out of 1 sheet.

Getting a 60" wide sheet is the trick
