I did a trackday at Snetterton yesterday my second one with the Phoenix, the first one was at Anglesey end of last year. I had gale force winds at
Anglesey and so didn`t really get to try the car out properly anything over 80 mph in 80 mph winds felt like my head was going to come off.
Yesterday at Snetterton it was a lovely dry day with light winds and what I was finding that on the 2 long straights anything over 100 mph and my
helmet was being buffeted enough to struggle with vision and judging braking points. Has anyone else experienced this and cured it. I only have a
small Perspex aero screen about 6" tall is there a larger one that will fit reasonable should I invest in a duckbill helmet or try and develop f1
style neck muscles.
Any suggestions or known cures welcome. 
Are you using a bike helmet of a proper car one?
Bike helmets are prone to this, bike riders heads are tipped forwards. That's what I try to do.
Car helmets are fine.
As above, Sounds like your using a bike helmet. Get a car helmet, most come with a very small chin spoiler, it does the trick and you won't have the problem again.
Is it possible to fit some form of "spoiler" to a bike helmet to make it more suitable to a kit car?
I have a bike helmet and was looking to buy another but this time with a built in sun visor....but if a car helmet is better, maybe I need to find one
with a built in sun visor if they exist?
Cheers
The buffering is caused by the flat windscreen. You either need to get a curved one or take it off.
I would say take it off and try it. My Striker was the same, buffing my head giving a sore neck. On my MNR no screen and a constant blast but no
side to side and much more comfortable.

Yes I`m using a Bike helmet. If I tip my head forward as much as possible so I could still see where I was going it did help a lot.
So one of these should cure my woes then.

I use a bike helmet, no problems at all. I think the problem will be with the car screen. I used to run my car with a full windscreen, and the buffeting (no side screens) was much worse than my current aero screen.

Can see my screen in this pic.
This is the perfect helmet for your application:-

Had the same problem in my Cobra - anything approaching 160kph the shaking caused my vision to blur - fitted high back seats and dropped my bum height
an inch or so and problem solved right up to 200+kph which is the highest speed I can reach on Killarney track in Cape Town.

These are OK...

I've got one of theirs but without the chin spoiler. Quality is good and more importantly so was the fit. Play-Kool are usually at stoneleigh
show, so you'd get a chance to try one on there.

imo it has mostly to do with the screen in relation to your seating position
try a temporary thing in enlarging the screen in the centre of the drivers side by some perspex .
you can fix it by some clamps , make a test drive see if there is a differnce. can you drive the car on the road?
Unfortunately the link to the pic of your screen doesn't work for me.
My Phoenix has the wrap round screen that extends part way down the sides of the car.
I have a template if you would like a copy. You could make on an inch or two higher. Or longer even.

The sunvisor is carbon screwed to small tabs welded to the cage during construction.
The seats are Westfield items. I had to trim the side flanges on them.
Just back from a Cadwell trackday. I bolted on a Perspex extension to my aeroscreen only extending it by approx. 50 mm in front of the driver. Cadwell
only has one place where you can reach 100 mph +. There it has reduced the buffeting to almost zero and I could easily spot my braking point.
To be 100% sure its cured I could do with trying it somewhere with a longer straight but it is definately a huge improvement. I am still using the
same helmet aswell.
Cheers for all the advice guys.
I would make one like Spyders but I`d have to have a new cockpit cover made aswell.
