Which material for aeroscreen ?
Just wondered what people had used to make their aeroscreens out of ?
Glass (does it need markings for SVA ?)
Perspex ?
Acrylic ?
something else ?

As you probably won't be actually looking through it, just over it, make it out of what you like (Check SVA re eye to top of
"deflector" angle to be on the safe side.

What determines "eye" level ?
Mine (5'7" tall)
or the SVA inspector (6'4" tall, 4'7" tall ??????)
must be a standard they follow ?

It involves a metal frame and a block of wood! This sits on the seat and a sighting taken across the top.
There's a diagram in the SVA manual, if anyone cares to copy it here...

The book specifies eye level.
I, if someone doesn't beat me to it, will put up a diagram next week.
Basically, a block is placed on the seat, a measurement is made vertically. From this point a horizontal line is "drawn" and a certain
number of degrees down gives you the answer!!
Can't be any more detailed, as it's all from memory, and I ain't got the book here!!
HTH though

whoooo
Do they really get the kit out to test this. I was thinking of putting the car through the SVA with the intended aero screen. May well just leave it
off until afterwards !!! Not risking a fail for the sake of poss. 1cm of screen !!!
thanks for the info

I was going to recommend Lexan but Conrod beat me to it.
Lexan is similar to perspex but is far less brittle. You can put some quite dramatic bends in it without it fracturing, heating it in an oven will
soften it alowing it to be formed over a buck, (we use MDF usually) and it will retain the shape on cooling. When drilling it use lip and spur bits
and go gently as it is prone to cracking if the drill grabs. Can't comment on price as I've never actually bought any but it would be my
choice of material if I decide to fit aeroscreens.

I'd also say Lexan. You can use a heat gun to heat make it pliable and then form it over your frame. Just remember that the side that you heat
will tend to be the outside edge of the curvature...
