Turning Off Wheel Friction in GTA: IV
Youtube user Dot12321 found a way to set the wheel friction values in GTA IV to a negative value, the resulting madness is documented in the below videos.
Turning off the friction in GTA IV means delving into your GTA IV data file which can be found in the ‘common’ folder of your GTA IV directory. Once there open up handling.dat and change the value for each car to a negative figure.
Or you could simply swap the file with this one , if you’re feeling lazy :p
