Since Live Free or Drive Hard and The Final Event are the two to cause the most aggravation for players, I found these two YouTube videos that help immensely. Both are platinum times, but if you watch them, you can get a very good idea for how to tackle any problem areas you may have. I looked at the speeds the player was carrying though corners, as well as about what time you want to hit certain sections at to give yourself the best shot at gold on those two events.
