^ I think it's safe to guess it is. The car is RWD, has 200hp, and only weighs 1100-1200kg's AFAIK, it probably needs the wing to make it more stable when putting power down out of corners.
Also, IIRC someone stated earlier that they should just change spring rates rather than adding a wing. I disagree - the characteristics of a wing are different from that of just changing spring rates, a wing only acts at higher speeds, so you can get a different weight distribution while moving, for stability. If the car creates no downforce/lift the weight distribution will be the same moving as it is when it is still (static weight dist.). In all truth, the weight distribution while moving is much more important than the static weight distribution.
