Exit the Options and go into Arcade Mode. 4. Select any track (not street or dirt courses). 5. Select a GT1, LMP or Group C car. It must be those types or it won't work. 6. In the Driving Options, set the tires to Racing:Super Soft. 7. Start the race in either A-Spec or B-Spec and enjoy! And here's a video.
