Note: This procedure requires editing a game file; creating a backup copy of the file before proceeding is recommended. With a text editor, edit the drivers "*.rcd" files, vehicles "*.hdv" files, and player "*.plr" files in the game directory:
-You can customize your teammates' race craft ability. For instance, for driver stats change the line to QualifyingAbility=3.8. Note: Change to a lower value out of 6.0.
-To customize your vehicle's behavior, change the line to TractionControlGrip=0.35. Its value must be between 1.00 (high) and 0.20 (low).
-Use the following changes to customize the AI ability for races with harder game play without compromising realism. For instance, keep engine power output the same but modify its mid corner grip. Change the line to AI Corner Grip Usage="0.89000"
