In NASCAR Heat 4 we’ve updated and added to our driving aids to give you more granular control of your racing experience. Under Options/Driving, you can change your difficulty pre-set which will set your assists and pre-defined levels, or you can choose custom and set your assists yourself. There are 6 assists that range from 0-100. There are full descriptions of what each assist does in the Options area. These can also be tuned from the pause menu during a race, so you get instant feedback on how each assist affects your driving experience.
