The TON Rally America cars use the MSport S2000 wing. The one being sold on FB from the white Fiesta isn't exactly the MSport wing, but something that is very close. I can't remember the company that makes it, but I think they are out of Italy. The Fiesta ST spoiler needs to be removed and the non-ST spoiler (not really a spoiler, just some trim) needs to be added. This shortens the overhang of the spoiler.
