A question about VG placement -
Most of the VGs on cars are placed on the roof, in front of or close to the rear edge before the window. I recall seeing a wind tunnel graphic here that showed recommended VG placement past the point where the body begins to taper - not before it.
Aren't you trying to hold the air down onto the tapering area (where it wants to separate)? Seems that placing them up on the roof would stop the air from following the taper and make the wake larger. Does Mitsu use them on the Evo just to make the wing more effective?
Wouldn't placing them on the front edge of the hatch/window of a hatchback (not the roof) be where they would do the most good? Doesn't seem like they would work well on a sedan.
