Full simulation (I beleive) is driving with the force feedback in the options menu left alone at 5. Then at your pre-racing driving menu leave driving assist or whatever its called off. This will allow you to feel understeer, oversteer, bumps in the road, rough suspension set-ups, and lastly when some one runs into you when racing. This will feel like a real car with no power steering, to me at least. The key to be successful with your new wheel is holding onto it good, so sudden jerks don't spin you out, and countersteering in whatever situation you find yourself in. You should find, like me, that this wheel is realistic and that is probably the best investment you made for this game : ) You might want to consider purchasing a cockpit or building one for a realistic feeling as well.
