SLIPSTREAM INTERNATIONAL - WORLD SERIES '25 S4

Overview:

🏆Championship structure:

The championship runs for 8 rounds with a mix of normal races (60 minutes), sprint races (2x30 minutes), and endurance races (90 minutes). 

The final race of the season (Round 8) is the Title Race. The track will be randomly drawn out of the tracks we don't run after round 7.

Because of the length of the championship and our approach to it, we allow 2 dropout rounds. That means that if you run all races, your 2 worst ones won't be counted.  

🏁Race format: 

Each race event features:

  • 30-minute official practice 
  • 5-minute Drivers Briefing in Discord 
  • 20-minute open qualifying 
  • Followed by the race 
The race will consist of one of four formats:

  •  Normal Race: One 60 minute race (normal points system)
    • These races will have a 50 minute pit window if there are mandatory pit stops.
  • Sprint Races: Two 30 minute races (half points for each race)
  • Endurance Race: One 90 minute race (double points)
    • These races will have an 80 minute pit window if there are mandatory pit stops.
⚔️Competitiveness:

  • Extended LFM BOP will be used in this series. This extended BOP will include all previous generation cars (e.g. Lexus, AMR V12, etc) based on LFM's Hotlap BOP Prediction.
  • Three classes will be created: PRO, PRO/AM and AM. You are required to complete at least one pre-qualifying hotlap on the pre-qualifying server. This is what we will use to determine your class. If you do not complete this lap, you will not be eligible to race.
  • If you join mid-season, you are still required to complete your hotlap. You will not be eligible to race if you don't complete it.
  • You may be subject to a class change if the admins deem you to be out-performing or under-performing for your class. 
🌧️Weather conditions: 

  • We will use real life weather as a reference to set the conditions. This means it may not be the same as real life conditions, but it will be accurate to possible real conditions. 
🛤️Practice Server: 

  • Practice server will be always set up one week in advance, after the completion of each week's race.
  • The communication to the drivers will contain the server setup details like: - Cloud coverage ⛅ - Rain probability 🌧️ - Weather randomness 🔀 - Time multiplier ⏱️ - Temperature 🌡️
🐕‍🦺Assists:  

  • All tiers will have the maximum stability control setting to zero and auto-steer disabled. Other than the ones mentioned here, all assists are allowed to be used.
🗺️Regions:

  • Our Assetto Corsa Competizione PC championship runs on a very particular schedule that enables all Europe, Africa, Asia and Australia to compete. Drivers from all around the world are allowed to take part in the leagues, as long as their connection is suitable enough.
👮Stewarding and live streaming: 

  • All drivers will be required to join the driver's briefing stage in our discord server after the conclusion of FP1. 
  • While we won't be broadcasting, we encourage all drivers who are capable to stream their POV of the race. 
  • The stewards will use contact logs to hand out penalties, but if you have an incident that you believe needs to be looked at, please contact the stewards.
  • The stewards can and will hand out penalties without reports if they deem it appropriate and necessary.
DLC WILL BE REQUIRED TO COMPETE IN THIS ENTIRE SERIES 
Participation in this championship is free of charge. To participate, you must join the Slipstream International Discord Server. All events are run through this server.
