High speed pit road
Note: This cheat involves editing a game file so make a backup copy of the file before going on. Then use a text editor to edit the right tracks file in the "tracks" folder in the game directory. Find the "Race Control" heading, then find the "speed_limit_MPH =" line. Change its value to the speed that you wish to legally go down pit road. Note: If you set the limit higher than 70, the spotter will still only say 70 as you come into pit road. Just ignore this and go as fast as you set it to.
