I would loosen it up a ton, probably about 11.00 right side track bar in qual and 12.00 in race trim (in fact, I'd rather leave the track bar as it is in race trim and add rear spring split instead to leave some adjustability in the car for running with low fuel at the end, but I have no idea how much spring split I would need to achieve the same balance change). Furthermore I'd go a click up on diff ratio and down to 45% tape in race trim.
