Well, if that's what you wanted then you should have gone with one of those dynamic aero wing setups that you can change on the fly from inside the cabin. I don't know if you've seen them, but they even have split wing setups now that can move the left and right side of the wing independently to help you in cornering. I know its overkill...but....that's the name of the game isn't it?
Quick detach is a great idea, but just make sure whatever mechanism it is...that it can withstand 1800lbs of force too hehe. Hey..if you got an dynamic wing you wouldn't have this problem of super high df at high speed...just set to 0 angle of attack and go nuts. That's what Bugatti does with the veyron; wing gets lower and flatter to minimize drag. Would be awesome if you had an airbrake!
