Back when I was in tech school for auto mechanics, I overheard a conversation about how a spoiler lifting up on the back would give you better control in a FWD. I couldn't believe what I was hearing. I felt it was my duty to enlighten them on the fact that it wouldn't help you with traction (thats really only a problem for fwd during initial acceleration and there is no wind then...) and would actually make the car unstable as hell due to the fact the rear would want to slide out from no traction.
They didn't believe me.
