High speed pit road: Note: This procedure involves editing a game file;
create a backup copy of the file before proceeding. Use a text
editor to edit the appropriate tracks file in the "tracks"
folder in the game directory. Locate the "Race Control"
heading, then find the "speed_limit_MPH =" line. Change
its value to the speed that you want to legally go down pit road.
Note: If you set the limit above 70, the spotter will still only
say 70 as you approach pit road. Ignore this and go as fast as
you set it to.
