1-Finish hybriding your car and export it to an ini file.
2-Go to the folder where u saved the ini, and double click on it, it will open in notepad.
3-scroll down in the ini to lines 292 and 296. 292 is front DF and 296 is rear.
4-Change the values for those lines to the desired DF, IE:
292=-201
296=-211
would be front DF=2.00 and rear DF=2.10
Note that the actual line values have no decimal point, and the value is 1 greater than the actual DF, IE: -201=2.00
After U change the values, save the ini, and then import the ini into MK's over the old car. Then if u scroll down in the program window to the DF lines it will show the new DF. After this U can still change parts with the exception of the body, as when U change a body it will set it to the default DF for that body. Write the new save and upload it with the sharkport.
