yeah, the VG looks cool....but does it actually have any functional purpose like the one on the IX? the IX's VG was wind tunnel tested with the wing, and was made with the fins positioned to increase downforce over the rear wing and clean up turbulence. The X was said by mitsubishi to not need a VG because of the diffuser under the rear bumper. So even though it looks good, was it ever tested to help the car's aero, or is it really just a decoration piece that is probably making things worse?

lol i dont have a wind tunnel to test it out but from driving it over 70mph+ i do feel the car more stable and steady . yes its true that the IX VG has the fins angled, that is because of the huge drop the evo 9 has from the roof to the trunk, thus needing more turbulence; the Evo x doesn't have that huge drop. A VG isn't making things worse, its not going to fudge up your 1/4 times. i personally got a VG because i like the way it looks on the Evo 10, it goes perfectly with the diffuser under the rear bumper.

the VG was put there to smooth out the turbulence, not cause more of it. Also, I wasn't talking about 1/4 mile times because I'm not a drag racer, and the EVO is not a drag car. I'm talking about downforce. Downforce matters in cornering, not so much in a straight line. I'd just be curious to see how the air behind the car is changed by this addition when mitsu said the car's aero has been tuned to not need one.

wrong again lol. they don't cause turbulence. turbulence is NOT good for aero. turbulence causes drag. the point is to create downforce while minimizing, or eliminating drag. the fins DIVERT, DIRECT, and CHANNEL air flow downward, and over the rear wing by generation of small vortices behind the fins. they don't delay air flow. if they delayed flow, that would be causing drag, and slowing air flow which is never a good thing. The only thing they delay is flow separation and aerodynamic stalling due to turbulence. they create small vortices that channel the air over the wing instead of letting the air travel in all different directions and cause turbulence.

The APR and FQ pieces are most likely designed that way for a reason, and have been tested for their performance rather than appearance. Vortex Generators are supposed to be small, and thin. the Rexspeed piece is all show, no go. a non-performance copy of a performance piece...rice.

i shall retort:
you obviously have no idea what real carbon fiber molds should look or feel like. by your statement, body panels on the mclaren f1, zonda, slr, ccx, et al. are all "cheep." the most expensive carbon parts are supposed to be quite thin, because they are dry molds, adds minimal weight, and does not crack when a kitteh sneezes on it.
actually, it's a chargespeed replica, not a fq replica. the fq has fins that point toward the rear wing's mounting points. chargespeed/rexpeed is straight. i won't argue the effectiveness of them though.

I do know what real molds shoud look like, It doesn't matter. I'm just saying IMO the thin carbon fiber like apr, looks cheep and fragile.

No sh@t they have performance in mind, IMO they look to small and cheap.. People who get VG's get them for looks, if your a pro and go racing everyday get the curvy VG that improve your lap time by .3 of a second. As for me this VG looks great for my everyday drives and occasional track days
...but you can't take the ricer out of the kid.
