here's my personal advice, DON'T use steering assist even if you are keybod warrior.. I started the game using keybod, NO steering and NO braking assist, or else it won't be fun, it'll be like the system controling the car for you.

The only assist i used during keybod days was TC,SC and ABS..

Now that I'm on steering, I prefer to off all assist..
Keep in mind this game consist the simulation element in it, so don't bring the high speed arcade racing habit of other previous NFS to this game, its not the same..
