Wind wings, doors, wind deflectors, bikini tops, hard tops, anything to manage wind buffeting. Aerodynamics has its own forum.

Adding a roof did wonders...

This is elsewhere but since it also qualifies as "wind management", it's here as well. Adding this reduced wind buffeting by about half.

In hindsight it makes sense. The air flowing over the top edge of the windscreen generates low pressure, which then sucks in air flowing past the sides of the windscreen. The side flow curves inward, pummels the driver. So, eliminate the flow over the top and it reduces the side buffeting, and it does.

I've been planning to make mine have a trans-top* roof from the get go, replacing the "X" member with a (wide) capital "I" shape. Two parallel beams with sheet metal or webbing between them to provide some diagonal rigidity.

This photo of the roof scoop leads me to believe it will still look good with an "I" instead of an "X" roof.

*I have an admittedly ambitious idea to give it something that resembles gull-wing doors, but instead of opening "up" they open "down" and turn into stairs to climb in.
