I use a controller and I have to say this is the best controller tuned game I have ever played. I'm on pc. Only thing I could think of is adding a visual representation of my steering in the menu that shows the the steering -100 - 0 - 100. Such as a steering wheel image that rotates just to give a better representation of your changes.
could some one clear up the center diff without torque bias like on 2000c cars. I know how a diff works and how it affects a car on the front and rear im just not sure of the effects of the center diff lock/open as forza usually just had a simplified diff with just torque bias.
