Not to be the devil's advocate...but I hate threads like this...
No true business venture is going to come about from a bunch of forum guys making suggestions about a wing...its just annoying to hear "I would totally buy it"...because in reality, maybe 5% of these people will actually buy, so be careful in estimating the demand via a mustang forum.
Also, the market for mustang parts is so incredibly saturated that attempting to enter this market selling one wing will never amount to anything. The only way this will get off the ground is if someone develops a prototype design/gather market research/ROI figures, and somehow gets one of the big players like Cervinis/ABCexclusive/etc to hear you out. Those companies are the only ones capable of producing something like this because they have already developed the facilites/distribution channels and have the assets/competencies to bring this type of product to market.
So can we stop getting all exciting about this? Sorry to say it, but you are all going to be disappointed trying to make it happen this way.
Birel21y...you say you work for Kaminari...but you really need to approach this with a good business sense if you want to get anywhere with it.
