3. Can I update my lap time if I improve on it after I post my screenshot?

To ask:
4. I can't find an indicator for the HUD to show me where/when I go wrong and "dirty" a lap. Is it a thing of Forza 4 history? If I turn on Rewind and watch for the "Rewind" prompt will this amount to the same thing? And will activating Rewind but not actually using it still "dirty" a lap?
  1. You are allowed to use any car, as long as it's overall grade is not higher than that of Class A. Should you want to upgrade a Class C car to Class A level, you are free to do this.
  2. As per point 1, the car car be upgraded and tuned as much as you want, as long as it keeps within the limits of Class A
  3. You can update your lap times as much as you want/can. The cutoff will be Sunday at midnight, and no other times afterwards will be taken into consideration
  4. A dirty lap is indicated with an exclamation mark in front of the time. This is to indicate that you either went off the track with more than 50% of the car, or used any tools that will give you an advantage, like Mods and Rewind. So yes, using rewind will cause a "dirty" lap


I hope that clears up things for you.
