McCann makes the wing. Both Archer Racing and McCann sell the wing. It is identical to the ORECA wing, carbon fiber, weighs around 5 lbs, and the cost is like $6k. You cannot open the rear hatch with the wing installed. Also, this wing really works and you must balance the front with a big splitter.
If you are willing to do this, it is awesome on the track!
Happy holidays!
