A lot of people seem to fit these side flaps to their cars.........
I've only driven my car with no windscreen at all so far, so my questions are:
1) Are they necessary?
2) Do they work?
3) Is it worth all the effort of cutting and mounting them?
4) Is there an optimal shape and size?
5) Does anyone have a template of a proven suitable shape?
6) Polycarbonate, I presume?
A already have a set of hinges which I bought many moons ago so that's not a problem.
I've been hovering over getting some of these for a while now, with the screen on the passenger gets quite a wind blast (goes up your nose). The driver is OK as you arm on the steering wheel shields you.
The only thing that puts me off it that these would only really move the wind blast further back.
I dont yet have them on my Sportster but do have some on my old Roadster and they certainly do help reduce the wind around the windscreen. Will eventually get some to fit the Sportster but need to work out how they are going to fit around the hood.
I had them on my old roadster. They made a quite a difference to the wind buffeting when driving. I made mine out of perspex. I even made the fittings! But now you can buy the fittings and just cut the perspex to shape yourself. Well worth it if you intend to drive the car regularly.

I found another picture of the same car......
They're mounted on the windscreen uprights and I notice the windscreen wheelnut has been replaced with an ordinary nut.
I've made some for my car as an experiment.
I used 2 bits of 4" x 12" perspex I had laying about.
I bent the edge and used the windscreen knob and one of the bottom panel screws to hold them in place.
They stop the wind hitting you in the lug'ole, so I'll be making proper ones later.
Another thing I've tried is filling in the rollbar.
I seen windstop devices for MX5s and the like made from mesh, and wanted to see if they worked.
I used a piece of carpet, zip-tied to the rollbar and took it down the road.
It made a huge difference with hardly any wind at all.
It was so good that you can hold a conversation @ 80mph without raising your voice.
So plans are afoot to make a windstop out of lexan.

Thanks, Rob.
That's interesting. There is a light blue Sportster (John at Warwick?) that has the roll bar hole filled in with some kind of transparent plastic sheet.

They are sold for cobra replicas so there should be various suppliers about.
I paid £14.99 for a set of 4 hinges off eBay.
I've just checked the sellers shop but unfortunately he seems to have stopped listing things around July '08.
The next question is - what is the difference between Perspex and Polycarbonate? I noticed that polycarbonate seems to be used for wind wings nowadays - is it an improvement over good old fashioned perspex?
Someone make an old git happy and tell me what the difference is please :-)
BTW I used Perspex for sliding windows in my Spartan Treka many years ago. They lasted 12 years before the car went to the great scrapyard in the sky.
