Can anyone please tell me if there is a clever and easy way of optimising the angle of the caterham perspex wind deflectors as i don't like using the doors .When they sit at their normal angle they don't really work well ,but when are set at a wider angle them seem to work much better -has anyone else found that .At their normal angle they only work up to about 50 mph .
I tried using clear duct tape on the outer surface of the deflector to attach to the windscreen surround -ie to widen the angle to better deflect the wind .However this looks a bit Heath Robinson and i suspect wont hold for long especially at higher speeds .I'm hoping some bright spark will have already come up with a simple solution .
Thanks

Use a hair dryer to enable you to bend them more...
A very common mod for those that use the deflectors.

Personally I think the best thing for them is to throw them in a skip, but to answer your question most people dip them in hot water as the heat will be applied more evenly than a hot air gun of hair dryer, then as Steve says, just bend them more.

I used hot water with mine but they wouldn't bend. A hair-dryer might prove more useful.

They're fine on a track when you've got a full helmet on, but I found them rubbish on the road. Eventually I'll go aero for trackdays, but the deflectors are a nice halfway-house for now.

I think the hot water has to be almost boiling and sit the deflectors in there for about 3 minutes. Then press it over the top of something like a kitchen worktop to get the shape.

It's something I plan to do with mine but not got round to yet. The above came from a club member who had done it, I think there needs to be quite a bit of bend to make it effective.

Easy to assess how far the deflectors need to stick out from the windscreen by driving along and pushing them into the airflow. They need to be a long way past where they are as standard - think of where they sit on Corba replicas...! Easiest / fastest way to bend them is using a hot air gun for a few seconds. The pan method works but does take a bit of time and they cool down quickly. Use a stick on protector or a bit of insulation tape to stop any damage to your scuttle when in use

Thanks for all these suggestions -ended up using the boiling water treatment in the pan on Sunday and managed to bend the bottom bit into a C shape -problem then is that the pins are really tricky to fit into the windscreen attachment . I was wary of trying to bend them too much in case they snapped .
Do i need to try and bend the whole deflector into a U shape along its vertical axis to make it effective -to be honest im not quite sure what im trying to acheive here -what i do know is that when i push the deflector away from me towards the screen it works much better .
Then went to test drive them -which was on reflection a big mistake as i got rather wet and the car was covered in mud inside and out [ -anyway the deflectors still seem rather ineffective at say 70mph and above . The good thing about the deflectors is that it means i can attatch a mirror to my roll cage -the doors don't have the mirrors on them . While driving with the deflectors i needed a beenie hat and a cap on top to stop the draft .
So I think ill try it out as a suggested with an open helmet and shades on - although i guess that's going to a bit tiresome on a nice hot day -not that there are many of those in Scotingland .Also I think I'm going to feel rather self conscious driving with a helmet on public roads in a 7 -does anyone do that for road use ?

Also has anyone tried using the deflectors with the half hood and or half doors ie with full windscreen -do either of these that make any difference to the turbulence ? Im guessing prob not but thought id ask in case anyone has experience of this first hand
