Airtabs or Vortekz?

[Heavy Armor]

Okay, so here's my plan. I'm going to install some VGs on my Mustang. Right now, I plan on adding some Airtabs to the edge of the trunk, since that's the area they were designed for (blunt edges). However, I would also like to add VGs to the edge of the roof, just above the rear window to prevent boundary separation before it gets to my trunk edge.

I prefer the look of the Vortekz fins, but I dunno if I trust the product. They basically ripped off the research that Mitsubishi did for the EVO, and who knows if they pulled it off correctly or not? The Airtabs have a lot of simulation and wind tunnel testing behind them, but are going to look pretty clunky up on the roof of my car, and this isn't really the application they were tested for.

So, just looking for some input from those of you that have seen/worked with these before. Which product do you think I should use on my roof?

Aw, crap. I just saw there's another part of the forum just for aerodynamics discussions. My bad.

A VG is a VG is a VG. The airtabs will work fine on the roof of your car. If you don't like how they look, then use something else.
