Wind Buffeting

[mpgainer]

Anyone figure out how to reduce the wind buffeting at high speeds on the track? My track requires us to keep our windows down and above 100 or so the buffeting is brutal. I would imagine many of you experience the same. I have wind foils from Blackmill on one of my other cars, and they work great. Unfortunately Blackmill doesn’t make them for Mustangs. Anyone come up with anything?

Anyone have a picture of these installed? After 7 years of tracking motorcycles I don't even notice the buffeting in my car by comparison

The groups I run with allow windows up or down, your choice. Sure is nice at 147 mph with the windows up! Gets warm in the car, but no problem for a 20 minute session.

I decided to buy the Blackmill wind deflectors. I purchased the size that I have on my 911 (991). I took measurements and they are really close so I figured it was worth a shot. Here are some pictures. Not perfect, but good enough and very effective at high speed. I’ve had the car up to about 135mph and the buffeting is essentially gone.

I 3d printed some of my own design. You can see them in this photo if you zoom in a bit.

Is that a windshield ice scraper? It kinda looks like one. New use for a winter tool?
Though since I see you're in SoCal I kinda doubt it........

No, just some cut and bent Lexan.

Exactly! I have the same “problem!”

Do you have a closure? If not add one. Its weird but with seats putting them down helped, with roll bar and no seats adding the Gt350 closure, or as on my race car a bulkhead stopped the drumming. Or put the deflectors, I haven't used those though.

Yes. In place of the seats is a flat piece of carpet. Here’s a picture. I could easily remove it, however the wind deflectors I put on seemed to fix the problem (at least up to about 135 mph).

That's interesting, I had the opposite experience.
When I had a full interior still and rear seats up, zero buffeting. When I removed the rear seats for the roll bar, then I had buffeting
