I've used the car a lot but havn't gone on any open road trips
so I havn't had the need to use the side curtains. But a constant problem has been keeping my cap on with the wind buffeting. And on a car without sun visors, a cap is pretty useful.
So I whipped together some crude wind deflectors, size determined by acrylic bits on hand, total project time just over an hour. I was curious to see what they'd do in the way of smoothing out the air flow as they can be left on all the time.
I developed and calibrated a sophisticated instrument to measure their effectiveness. I call it a Captrometer. It's calibrated like this: 0, cap flies off and is lost; 1, have to remove the cap because there's no way to keep it on; 2, have to keep grabbing the cap; 3, feel like you're about to loose it sometimes so you grab it to make sure it doesn't fly off; 4, wind effects are diminished to the point you don't feel the cap will fly off unless you unload the suspension at high speed and gravity wants to help the cap fly off
; 5, cap stays firmly on head.
I'm really happy with the diminished buffeting. I'm giving them a 4. The materials pretty thin but it was free. Now that I know they work so well I'll probably make some with a little thicker lexan.
Great day for testing the deflectors, Molly Maid girls asking to switch cars with me, flag girls giving me the thumbs up and the usual "love your car" as you drive by. Ah, life is good, wind deflectors are good
