That 10 foot long gutter that I installed the other day,
http://ecomodder.com/forum/showthrea...suvs-5140.html
came home tied on that roof rack..
Back in January of 2000, I ordered and installed those myself.. They are there to stay.. (Loctite)
From what I have learned so far about VTs (like AirTabs) is they can add drag.
Don't need any more high profile stuff sticking out into the air flow..
I might want to add some ZZ tape just ahead of the tail lights, to keep the flow attached until it gets to the back edge of the Wake board..
The top piece is pretty streamlined, so it will likely stay attached up there..
No real testing yet. Did 25 miles last night, but traffic conditions were bad and the test wasn't what I wanted. I did get a pretty good 31.2 MPG anyways..
And, no.. I don't know what I'm doing..
