I hope to cover the whole car in tufts by this weekend and get some footage of before and afters with the vortex generators in various locations. Right now I'm using braided nylon string but I think its a bit too heavy and I am going to try to find something lighter and more responsive.
I'm really glad they ended up working so well, I would have started a Kamm back if things would have went sour. And these VG's look really cool
