I think that as long as you are within the spirit of the rules, unless you are a top contender, it shouldn't matter. The rule was designed to discourage the wings a lot of the New generation cars had on them, which to say the least, were ridiculously huge. One of the Older Camaros even had a Wing that could articulate to provide reduced drag at top speed or increased downforce during braking and could split on two planes for cornering. The wing had been banned in many other series, and not it's banned there as well.
