Got them on all mine. Its good with the windows just cracked, but still buffets with them right down.The interior gets a bit boomy when driving with the windows down. Has anyone got any experience of using wind deflectors and a recommendation for supplier?

That's brilliant, I think you are the first, will try it next time out if I remember! - AndyI have exactly the same booming noise problem. It really does our heads (and ears) in. Our car don't have AC, so windows are the only practical source of cooling and ventilation on hot days.
I've been thinking wind deflectors too, which would hopefully add the additional benefit of being able to have windows cracked an inch or two on rainy days.
But I don't fancy the problem with (a) them stopping the window closing properly, (b) them having no effect on the booming noise when windows are open wide, and (c) them causing their own turbulence noise.
Has anyone solved either of these three issues?
One interesting thing I have discovered is that if the flow of air is redirected or interrupted around the open window... the noise stops. This can be done very simply with your right hand. Try it. Window fully open... get up to speed... 50 or 60mph plus.. move open hand in various positions around wing mirror until the sweet spot is found and the noise stops.
So next question is... as I cannot be the only owner to have sussed this.... is there a deflector available that'll mimic what the hand is doing to air-flow around the window?
I've tried opening the rear windows and it was just as bad. Maybe I opened them to far, so will try again.As above, opening a rear window a couple of cm has a huge impact on the boom.
Very interesting, please share some photos when you feel you have found a good design?It works!
Tried it today with an 8" x 6" rectangle of thin clear plastic cut from a 2 litre spring water bottle. Offered it into the drivers side door seam, longwise out, just in front of the door mirror so that the curve of the plastic bottle side caressed around and a little beyond the neck of the mirror.
Got up to 60mph and fully opened the driver's window and that hectic thrumming oscillating sound had gone. My hyper-critical wife pointed out that it was still noisy... but also had to admit that it was the same volume of noise you'd expect from an open window at 60mph on any other car; which will get noisy from the streamlining being compromised. We did a control by maintaining 60mph, closing the drivers window and fully opening the front passenger window, and the result was a return of those extreme rapidly oscillating pressure waves that do your ears and head in.
I just need to try trimming the piece of plastic down to the minimum size that still works, then replicate it in perspex and tape it to the inside edge of the door pillar and hope it don't look too Heath-Robinson.
Will do, but don't hold your breath as it is way down the list (both car and non-car) of my current priorities.Very interesting, please share some photos when you feel you have found a good design?
My solution is to open the front passenger side window and driver side rear passenger window. Wind is then sucked diagonally across the car interior cleanly due (I guess) to the dynamic pressure difference and buffeting/booming does not occur, even with large openings. Not so convenient as you have to be a bit double jointed to reach behind to wind down the passenger window but it definitely works.I have exactly the same booming noise problem.

Thanks for that suggestion Bluesim. I can rationalise how that would work.... positive pressure at the open front window and negative pressure from the rear window diagonally opposite it, causing a small refreshing hurricane blasting through the car.
