I would adjust the car to height preference and stance that you like and not worry about the difference in frame height. Having got it set up where you like it and it works without rubbing (too badly) etc check the caster angle of the front end on an alignment machine. Tire pressure sound close, watch the tire wear carefully for a while and make sure it is uniform. The wide tires are prone to bulging out the centre of the tread with too high a pressure.
