Yes I do. I was literally not sure if you were being serious or just making fun of the big wing.
Looking at the picture the wing seems to have a pretty big curve to it, but also a high amount of angle to it. The end-plates are far forward, but the center of the wing appears to be in a good position. Thing is, while the air might be cleaner where the endplates are, the wing would still be more effective if it were straight. But I do think it would be effective.
This wing is even further forward:

But I'm sure this wing has had a lot more wind tunnel time as well.
Considering I don't plan to track the BRZ, if I were to do something silly like spend the money for the body kit above, the wing would be for show, or even not on the car. I think it would just as good or better with the simple TRD or 5:AD duckbill.
