Note: This procedure requires editing a game file; creating a backup copy of the file before proceeding is recommended. Enter the "vehicles" sub-directory that is inside the game directory. Use a utility such as WinZip or PKUnzip to extract the "physics.txt" file from any of the .zip files. Use a text editor to edit the "physics.txt" file and change the "//idealMaxSpeed" entry to "200". Save the file and add it back to the original .zip file. The top speed bar will be full for the vehicle when the game is played.
