E86 polycarbonate windshield

I want to gauge interest in buying a polycarbonate windshield from those of us in the US that track our Coupes.

I'm looking to replace my windshield with a lighter and stronger polycarbonate (aka Lexan) windshield. Mine is now pretty pitted and has a cateye. At the moment, the only source I can find is Plastics 4 Performance in the UK. I bought my rear window from them. They make good stuff, but their windshield is a bit pricey compared to US sources of polycarbonate windshields. Shipped, P4P wants $900 usd. For comparison, Racing Shields in Indiana charges about $550 for a hard coated windshield. They make a windshield for about every BMW that sees track use from E30 to E92, but not E86. I've had a conversation with Peggy at Racing Shields and she is willing to consider making them if there is interest.

At this point, I'm not looking to put together a group buy, although I suppose that could happen. It would certainly be helpful if I could let her know how many she may be able to sell if they invest in the mold (basically they just buy a glass windshield and melt the polycarbonate onto it's shape). Or maybe better yet, if you have interest give them a call so she hears it first hand.

Would these require center supports or would it mount like OEM? if it mounts like OEM I am 100% in. I like the idea of buying from the Racing shields because of that "supercoat" option they have.

Anyone know the weight of the stock windshield? Might have to do this and the carbon roof.

EDIT... RealOEM says 22.1 pounds for the OEM screen. 11 pound weight savings would be pretty nice.

Not sure. At 1/4”, I believe it may not need support. A friend is running one in an E46 without support and reports a bit of wobble. But the E46 windshield is larger with less curvature. I’ll probably fabricate a center support out of carbon fiber just because. It’ll be a cool little project…

I'll try and hit up Peggy today and see what she says on the subject. If I can get away with out a support I am totally in for this. I figure about 10 pounds can be saved with the screen and another 7 with the carbon roof. 17 pounds off the top of the car is not too bad!

I love the idea, but for me it's not feasible due to where I live. Keeping the glass front screen due to huge amounts of sand in the air. When I move back to Oz , I'll be all over this.

Racing Shields never came through, so I gave up on them and ordered a windshield from Plastics 4 Performance in the UK. Received it today. I haven’t opened the box, but can say their rear window I got a few years ago was an excellent fit. They also make the side windows.

Curious on time for delivery, cost, and ease of installation (especially the side windows). PM if you like..

Also, how resilient is this for track use and/or some street use? Any issues with fogging or micro scratches, etc?

P4P is pretty quick to ship. I ordered it Oct 14. So 4 weeks. Cost was $1,023. The lexan has a hard coating (“Enduro”) that they say is scratch resistant, but I plan to use Protint protective film anyway. They offer an anti-fog coating but it’s nearly as much as the windshield. Dawn dish soap works just fine.

As for fitment, I won’t know for a few weeks as the car is loaded up in the trailer for the next event at the moment.

Check your local laws for street use. Lexan will not be DOT approved.

Oh that's a nice film.
Did you put a window tint film in the rear lexan too? It looked darker than normal.
