Aren't these store-bought VGs? (though they're the only ones i found that seemed to work.)
*Yes,I caught the part about the mini boat tail.And I was trying to emphasize the importance of where the trailing edges terminate to guarantee reattachment WITH the VGs.
*With respect to the VGs,I understand that Mitsubishi designed the units used on the Lancer.
*VGs on mirrors are usually the result wind noise discovered in an acoustic wind tunnel.The VGs can alter the noise signature of the mirror and may not be intended for drag reduction.Again,with a mirror,there would be no structure for separated air to reattach to,just like the semi-trailers.
