It is also possible that you do not have enough power to overcome the g force in said corners. The way you can know for sure is just listen to the engone, i.e. if it just does not rev any higher then the g force is the cause, if it starts running like shit, then you are fuel starved. I personally have run into the g force problem in one of my previous cars, sticky tires, stiff suspension, and not enough power.
