Anniversary Race 2 – NASCAR 90s at Daytona

What is special about this event

Cause Dave Esotic made a plugin which adds "dynamic restrictors" or better "more realistic slipstream" to Assetto Corsa.

ACs drafting/slipstream logic isn't complete enough for cars driving on a super speedway, like Daytona, as it only models slipstream benefits for the car behind another car.
The app simulates the slipstream for a car pack...
Therefore it has to run on a Server and sends admin commands in real time to adjust restrictor values while cars are driving during a session.

I would like to thank Dave Esotic for his incredible support over the past few weeks.
He always had an open ear and even set up his own computer to provide us with a server with his app installed.
Thank you so much!

I would also like to thank TimoOne who was so kind to provide us a capable server, which can host Dave Esotics Dynamic Restrictors plugin.
Many many thanks!

And last but not least a huge thank you to Flashor, who will drive the Pace Car in this special event.

    Important information about the race procedure

    • Flashor or margar will drive the Pace Car
    • Rolling Start
      When the normal AC lights go out, the Pace Car will pass everyone and start the formation lap with a max speed of 150 km/h. The "Dynamic Restrictor Flag App" will show this information on screen.
      The pace car will dictate the speed. Means: All cars stay in starting formation with a speed not faster than 150 km/h.
      Means the drivers with the uneven positions (1,3,5,...) take the lower line of the track, whereas the driver with the even postions (2,3,4,...) take the upper line.
      It is not allowed to pass the car in front. When we cross the start-/finish line the indicator flag turns to green and we can Go Full Throttle.
      There are no automated penalties for speeding during a rolling start. But if you overtake the car in front, it can be reported and sanctioned.
    • Safety Car
      During the race, situations will arise in which a Safety Car is deployed. The Safety Car leaves the pits and a yellow indicator show you that we are in a Safety Car situation with a max speed of 150 km/h.
      The leader lines up behind the Safety Car and the other cars slow down and as long as they are in the same lap, it is not allowed to overtake the cars in front.

      If a car is a lap down, then it is allowed to pass the leader and the Safety Car and to line up at the end of the field.

      All cars form a single line behind the Safety Car. This gives us an easier restart 😉

      When the track is clear, the Safety Car Driver informs you, that the SC enters the pit at the end of the lap.
      The "Dynamic Restrictor Flag App" also displays this on the screen.
      When the drivers reach the start-finish line a green indicator pops up and signals that it is allowed to go full throttle again.
      There are no automated penalties for speeding during a safety car situation. But if you overtake the car in front, it can be reported and sanctioned.
    • Pitlane Speed Limit
      In the pitlane you have to be slower than 80 km/h. If you are faster, you receive a drive through penalty.
    • Pitlane Crossing
      Do not cross the withe line. Enter the track behind that line. If not, you receive a drive throught penalty.
    • Penalties
      - Drive Through > just drive through the pitlane, but be careful to not earn a new pitlane speeding penalty
      - Investigation after the race > Penalties must be served during the race.
      If you don't clear a penalty or receive it in the last lap, the penalty time will be added by the admin after the race.
