Adrian, the car is setup with a AE thick t plate, it's actual dimension is .070, measured prior to install and noted onto the t plate with marker. It is assembled using two pod screws.
The idea of less grippy tire is noted, the objection being the the car runs well in all other portions of the track except the few turns that create this possible inside tire lift for only about a couple of feet max. If time permits I will try greens, I don't plan to order any so I will need to mount and true a set or two, just not much time to get it done right now.
Fast ho having what seems a similar type problem, and adding more roll stiffness to cure it is worth trying since it could possibly make other sections better still where maybe I don't notice it trying to lift the inside rear tire.
