My experience removing the entire rear wing was a 500 rpm increase on the back straight at Daytona. The lateral stability was diminished as well as downforce. Being accustomed to the handling of a formula 1 superkart I reinstalled the wing assembly less one of the 2 wing elements. I advise if you want that 500 of so increase you be prepared to do some other adjustments or just let the laydowns do there thing and do what your kart does best and finish. As far as I know, you will not tech without a wing unless you are in the unlimited class.
