0. Introduction

  1. The Sports Car Open is a racing league, which is organised and run by CoRe SimRacing on the Motorsports Simulation service. The series will utilise a selection of prototype and grand touring cars in a team-based, multiclass series running at different types of circuits from all around the world.
  2. While racing is obviously about competition and trying to achieve the best possible results, we would like to not lose the fun factor, since at the end of the day, it’s still the top priority.
  3. We also expect all drivers and team representatives to treat each other as well as members of the series administration with respect at all times.
  4. We are open to suggestions and constructive criticism as well as ideas and other things that contribute to improving the series as a whole.

1. Cars and Class Structure

  1. All Sports Car Open events will feature three different classes of cars. Each car class will include the following car models:
    Class Abbreviation Car(s) Ballast / Fuel Cap.
    Prototype P HPD ARX-01c 0 kg / 100% (60kg)
    Grand Touring GT Ferrari 488 GTE
    Ford GT GTE
    0 kg / 100% (90l)
    0 kg / 100% (98l)
    Grand Touring Challenge GTC Audi R8 LMS
    Mercedes-AMG GT3
    Ferrari 488 GT3
    0 kg / 75% (90l)
    0 kg / 75% (90l)
    0 kg / 75% (82.5l)
    1. Should iRacing release a new prototype car with similar performance characteristics to the current P class car, then the series administration can replace the old car with the new car if at least 66% of all teams in the class agree to the change.
  2. The series administration reserves itself the right to add ballast or limit the fuel capacity of any car or car class to balance the cars within a class or to modify the balance between the car classes. Such car adjustments will never be made any later than 3 days before the start of warm-up. Generally, no adjustments will be made, unless the series administration feels that there are overly dominant car models within a class or too small or large performance gaps between car classes.
  3. Should an iRacing update affect the performance of one or multiple of the cars in the championship, the series administration can alter or reset any of the previously allocated weight handicaps or fuel capacity restrictions.

2. Timetable and Season Schedule

    (20 minute duration)
    Sunday at 15:00 UTC Start of the Race
    (240 minute duration)
    1. Team sessions will only be used for the main event itself. Sessions held on days other than Sunday, like both free practice sessions, will always be single driver sessions.

3. Team and Driver Entry Requirements

  1. To be able to enter, every team must have a team manager as well as a driver line-up consisting of at least 2 but no more than 6 drivers. Team managers as well as other non-driving team representatives don't have to fulfil any of the driver requirements.
  2. All driving team members, meaning everyone listed on a team's driver line-up, must meet the following minimum requirements at the point of sign-up:
    Road Licence Class & SR C 2.00 or higher
    at the point of registration
    Road iRating 2000 or higher
    at the point of registration

4. Entry Procedure

  1. To enter the series, each team manager wishing to field one or multiple teams must register an account to be able to create these teams. For each team, all information must be filled in as required by the form on the website.
  2. Once a team has been created, the team’s status will automatically be set to “Pending” until it’s been reviewed by the series administration. Once this has happened, the team’s status will either be changed to “On Waiting List” or “Confirmed” depending on when in the season a team is created.
    1. A team’s status determines what about a team can be edited by the team’s manager. The “Confirmed” status will only let you edit a team’s driver line-up, whereas the “On Waiting List” and “Pending” statuses allow you to edit everything on a team.
    2. A team that’s created before pre-qualifying has taken place will jump straight to the “Confirmed” status as soon as the sign-up deadline (September 25th, 2017 at 17:00 UTC) has passed and will stay there if they pre-qualify for one of the slots on the grid for the season (provided pre-qualifying takes place).
    3. Teams that do not make it through pre-qualifying will have their status changed to “On Waiting List”. The same applies to teams that are created after the original sign-up deadline (September 25th, 2017 at 17:00 UTC).
  3. Each team’s driver line-up must be unique. No driver may be listed on more than a single car’s driver line-up. Should he wish to drive for another team, his previous team must remove him their line-up before he can be added to his new team’s lineup.
  4. No team will be allowed to have more than 2 entries in any class. The series administration reserves itself the right to waive this rule should the level of interest in a class be too low to fulfil the minimum car count.
  5. A team’s chosen name, team ID, car number and class will be locked for the entire season as soon as a team is given the “Confirmed” status. Confirmed teams may still edit their car selection within their class (in GT and GTC) until the sign-up deadline on September 25th, 2017 at 17:00 UTC. The only scenario under which a car change in the Prototype class would take place is described in rule 1.a.1 of this document.
  6. The total car count will be limited to 50 cars. While there are no strict limits on how big each class can be, no class will be allowed to have fewer than 12 entrants with the maximum car count per class being capped at 24.
    1. The exact allocation of car slots will be determined by the number of teams signing up for each class, but it will always follow the minimum and maximum car counts as described above.
    2. Should more than 65 teams want to enter in total, 2 pre-qualifying sessions will be held for all categories that require it. The number of available slots in each car class will be announced ahead of said pre-qualifying session.
    3. Should fewer than 65 teams wish to take part by the time the sign-up deadline (September 25th, 2017 at 17:00 UTC) has passed, then all slots will be allocated on a “first-come, first-served” basis.
    4. Exact details on how pre-qualifying is going to work (provided that it’s needed) are described in Section 6 of this document.
  7. Should a full season slot open up because of a team withdrawing or being withdrawn from the season, then the first team on that class’ waiting list will be promoted to the “Confirmed” status and will take up the vacant spot on the grid. Should this happen during an ongoing event, then their slot will remain empty until the following round.
  8. The application deadline for the opening round of the season will be on September 25th, 2017 at 17:00 UTC. Teams may still register after this point, but will only the have “On Waiting List” status and will join the end of the waiting list of the class they entered, behind all teams that failed to make it through pre-qualifying (should it have taken place).
  9. Teams that have the “Confirmed” status and are part of the grid will only be able to edit their team’s driver line-up up until 24 hours before the start of a rounds’ first free practice session (Wednesday at 17:00 UTC).
    1. Should a new driver take part in the race having been added after the deadline, the team will receive a 30 second stop-hold penalty once said driver has taken over the car.
  10. Any team that misses 2 rounds without notifying the series administration of their absence before the event will be withdrawn from the series.
    1. The same will be the case for any team that misses 3 rounds, whether their absence was excused or not.

5. Paint Schemes

  1. All teams are free to submit custom paint schemes, should they want to use one.
  2. When submitting a paint scheme, every team has to make sure to include information like the team name, car number and car model. All paint scheme files should be named as shown below:
    (XXXXX should be your team's ID)
  3. Should teams elect to use a paint scheme, they must send it to at least 24 hours before the start of first practice for it to be included in the lastest version of the skin pack.
    1. Please make sure to include your team’s car number, team name and car class in the subject line of the e-mail when sending the paint file. You may also send multiple paint files in a single mail, but please make it clear which paint is for which car in the mail itself.
  4. Custom decal layers, including the series number boards and class stickers for all cars, will be used no matter whether a team sent in a paint file or not. These decal layers will also be included in the skin pack.
  5. Custom paint schemes for any single driver session, like both free practice sessions and any eventual test session do not have to be sent in and will not be accepted or included in any kind of skin pack.

6. Pre-Qualifying

  1. If required, 2 pre-qualifying sessions will take place on Wednesday, September 27th, 2017. The first session will begin at 17:00 UTC with the second session beginning at 22:00 UTC.
    1. Every team can choose which session they will take part in, but they can only take part in one of them, with all rules below applying.
  2. The sessions will use the same circuit, track layout and time of day as the opening round of the season. The track state will be set to “automatically generated” and marbles will not be cleaned.
  3. Both sessions will begin with a 45 minute long practice session in which every team’s pre-qualifying driver can join with the correct team, team name, car number and car model.
  4. The 3 hour long open qualifying sessions at begin at roughly 17:45 UTC and 22:45 UTC respectively. Every team will be allowed to turn as many laps as desired in order to get the fastest possible lap time.
  5. Each team’s fastest qualifying time in that session will be their pre-qualifying time. The driver who set the lap time will be locked into that team’s driver line-up for the opening round of the season.

7. Warm-up

  1. Warm-up is the session in which all teams and drivers will be able to connect to the race server to prepare and drive practice laps ahead of qualifying and the race session itself.
  2. Teams will be required to register with the correct team and car, meaning that the team ID, team name, car number and car model have to match the information listed on the series’ entry list.
  3. Should a team join with the incorrect team ID or car number, they will be allowed to participate in the remaining sessions, but will receive a drive-through penalty within the first 20 minutes of the race.
    1. No penalties will be given to teams who had their car number taken away by a team that registered before them.
  4. Any team that registers with the wrong car model or even registers with multiple teams will be disqualified from the event and refused entry to the qualifying and race sessions.

8. Qualifying

  1. All qualifying sessions will be 20 minute long single car sessions with a maximum of 4 timed laps available to each car.
  2. As per iRacing lone qualifier rules, any member registered for the team will be allowed to qualify the car.
  3. The qualifying driver is not required to start the race, but they will be required to drive the car for at least 1 full lap (meaning it can’t be an out or in lap) during the race.
  4. Every car will be required to set a qualifying time. Teams who do not set a qualifying time or are slower than the fastest car of the class behind them will have to start from pit lane.
  5. The series administration may not allow a team to take the start, if they’re deemed to be a potential danger to other cars on-track during the race or if they haven’t set a fast enough lap time in qualifying (see rule 8.d).

9. Race

  1. All races will utilise the standard rolling start procedure the iRacing software provides with the following alterations:
    1. The class leaders of all supporting classes should keep a 10 second gap to the last car of the class ahead on the pace lap.
    2. Once iRacing waves the “green flag”, the P field’s race will be underway. The GT and GTC class cars must ignore the green flag as displayed by iRacing and must remain in their grid formation while also keeping to the pace car speed.
    3. The leader of the GT class will be allowed to initiate the start of their categories’ race by starting to accelerate away from the field once they’re in the “starting zone”. Once he has done so, all cars in the class will be free to race. The same procedure applies to the GTC class pole sitter and field.
    4. Images of the exact beginning and end points of this “starting zone” will be part of the drivers’ briefing, which will be published before the first free practice session.
    5. Teams that start from pit lane must line up at pit exit in a line. They will not be allowed to leave the lane until the race administration declares the pit exit open once the last GTC car has passed the first turn. Leaving the pit lane early will result in a 30 second stop-hold penalty.
  2. During the race itself, the fair share driving rule will be enabled with a minimum of 2 drivers and a maximum of 6 drivers being able to drive the car.
    1. As per iRacing rules, a “fair share” is defined as a quarter of an equal share.
      Example: 2 drivers with a total of 130 laps driven
      → 130 laps / 2 drivers = 65 laps per driver on an equal share
      → → 65 laps / 4 = 16.25 laps as 16 laps minimum per driver
    2. The minimum “fair share” lap count only applies to the number of drivers defined as the minimum required drivers, meaning only 2 drivers have to fulfil it in this series.
  3. Additionally, to make sure people don't take too many liberties with the track limits, especially at more modern circuits with multiple tarmac run-off zones, a formula will be used to calculate a team's maximum number of incident points.
    1. This formula will take both, the number of turns on the circuit as well as the number of laps driven by the team's car into account and looks as follows:
      Formula: (corners per lap * number of laps by car) / 25 = team's incident limit
    2. Using this formula, a team that's driven 100 laps on a circuit with 21 corners would be able to get up to 84 incident points before exceeding the limit. Fractional amounts will always be rounded up to the closest full number.
    3. Exceeding the incident limit will result in the car being disqualified from the race.

10. General Driving Conduct

  1. All drivers must pass in a safe manner and respect their opponents. Both drivers must also take into account leaving room for lag. This applies to lapping manoeuvres just as much as to overtakes for race positions.
  2. Drivers will not be allowed to block and must choose their line ahead of a corner without moving under braking to cover off any attacks from their opponents (blocking meaning that you're reacting to line changes of the car behind to fend off any attempts of the car behind to get alongside).
  3. As this is a series with multiple car classes on-track at the same time, all of which have varying top speeds, braking performance and cornering capabilities, every driver is asked to take care of the previous two rules as well as always acting with common sense.
    1. Lapping cars must at all times be aware of the fact that they are the ones who have to make the passes since they're the faster cars. They can't expect to always have the racing line when doing so and will have to be just that little bit more cautious every now and then to make sure they they don't ruin another team's race along with their own.
    2. On the other side, all lapped drivers must make sure to always behave in a predictable manner. They should stick to the racing line where needed, but that doesn't at all mean that they can't cooperate should they find themselves in a situation where moving slightly off-line or braking slightly earlier will help a lapping car get by just that little bit sooner and faster, helping both cars in the process by losing less time on the race track.
  4. Should someone go off the track, they have to make sure that the track is clear before rejoining the racing surface. Dangerous track re-entries or even causing an incident while you try to rejoin will result in penalties when reported to the series administration.
  5. Under a waved yellow flag, please make sure to pay attention to the road ahead as well as any potentially stationary or slowly moving cars next to or on the race track itself.

11. Server / Connection Issues and Race Stoppages

  1. If the iRacing service fails during an event resulting in drivers being unable to join or stay connected to the server or if the server becomes unstable enough to potentially cause problems for drivers, the event may be stopped or even postponed or cancelled. When this happens the series administration will announce the “red flag” status of the session both in-game (if the session is still accessible) and on the series Discord.
    1. Should the service experience issues during warm-up, a new session will be created with the series administration attempting to keep to the everything running on schedule.
    2. Should the service experience issues during qualifying, a new session will be created to give everyone the chance to qualify for the race under fair conditions. Again, the series administration will attempt to keep everything running on schedule, but should the issues result in a longer delay, the series administration does reserve itself the right to reduce the race length accordingly by up to 1 hour.
    3. Should the service experience issues within the first hour of the race, a new session will be created with a short warm-up, a new qualifying session a 3 hour long race. The less than 1 hour long part of the race will not count for points, only the results of the new session can count for points.
    4. Should the service experience issues within the first 2 hours of the race, a new session will be created with a short warm-up, a new qualifying session and a 2 hour long race. If the race has run for at least 2 hours, then the series administration can decide to declare the race and award half points based on the positions from the last completed lap before the issues arose.
    5. Should the service experience issues after 3 the hour mark or later in the race, then the series administration will declare the race and award full points based on the position from the last completed lap before the issues arose.
  2. Should the iRacing service as a whole be affected by server issues, meaning that a new session or a restarted race would also run into trouble after a while, the event will be called off.
  3. It will be down the series administration to decide, whether the event will be rescheduled, replaced or cancelled.
  4. Regardless of what decision is made under whatever circumstances, they will always be announced on the Sports Car Open Discord.

12. Protests

  1. Teams may protest any incidents they were involved in or affected by. The only way to do so is by filing a protest via the series protest form at any point after the start of the race to a maximum of 2 hours after the event ending.
    1. Incidents will be investigated at the earliest opportunity and will be judged by at least two different series administration members.
    2. The series administration will attempt to reach a verdict as quickly as possible, to ensure that as many of the protests as possible will result in the guilty parties being penalised during the race.
    3. Should the series administration not be able to reach a verdict during the race because there is too little time left in the race, the penalty (if applicable) will be converted to a post-race penalty.
    4. The verdicts of all post-race investigations will be published within 48 hours of the event’s conclusion.
    5. All protests and verdicts will be tracked in a spreadsheet and published once the results have been declared official.
  2. Frivolous protests will be ignored. Should a team be found to repeatedly file such protests, they may be warned or even penalised for their actions.
  3. The start of every race will automatically be reviewed by the race administration to check whether there were jump start or significant incidents.
  4. All protest verdicts are judgements of fact and cannot be appealed under any circumstances.

13. Penalties

  1. There are several types of penalties that can be assigned following an investigation by the series administration. The list of possible penalties can be found below.
    • Warning
    • Drive-Through Penalty
    • Stop & Hold Penalty (severity is down the series administration)
    • Time Penalty (severity is down the series administration)
    • Points Deduction (severity is down to the series administration)
    • Disqualifications
    • Suspensions (meaning exclusions from multiple events)
  2. Unlike stop-hold penalties, drive-through penalties cannot be combined with pit stops. Violations of this rule will in a further drive-through penalty.
  3. Repeat offenders will receive harsher penalties, should they be penalised for the same type of misbehaviour multiple times.
  4. Penalties can affect teams as well as drivers individually, meaning a team can just as easily be excluded from competition as individual drivers, depending on the severity of the rule violations they committed.
  5. Should any warnings or penalties be assigned during or after the race, then they will always be announced on the Sports Car Open Discord before being applied in the game or the race results.

14. Championship

  1. All teams who start a race, fulfil the fair-share requirements and do not exceed their personal incident limit will be classified in their achieved overall race position in the official results. Points will be given to the top 10 cars within each class.
  2. There will be three official championships in the series, one for each class.
    1. The Sports Car Open Prototype Championship will be awarded to the P team which scores the most points throughout the whole season.
    2. The Sports Car Open Grand Touring Championship will be awarded to the GT team which scores the most points throughout the whole season.
    3. The Sports Car Open Grand Touring Challenge will be awarded to the GTC team which scores the most points throughout the whole season.
  3. Championship points will be awarded to the top 10 classified cars within a category using the following scale:
    Class Position Points Scored
    1st 25 Points
    2nd 18 Points
    3rd 15 Points
    4th 12 Points
    5th 10 Points
    6th 8 Points
    7th 6 Points
    8th 4 Points
    9th 2 Points
    10th 1 Point
  4. In the event of a tie in points standings, the position in question will go to the team with the most race victories. If neither team has a win or not more than the other, the position goes to the team with the most second place finishes. If the same applies there, the procedure is continued until the tie can be broken. Should this not be possible, both teams will be declared champions.

15. In-Game Session Settings

  1. This section of the rulebook lists all in-game session settings that have not been brought up at an earlier point in this document.
    1. All sessions will be hosted on the NL-Amsterdam server farm.
    2. Dynamic weather will be used in all sessions.
    3. The track state will be always be set to “automatically generated” at the beginning of a session and will carry over to the next sessions on race day. Marbles will not be removed from the circuit at any point.
    4. Full course cautions as well as fast repairs will be disabled.
    5. All driving aids with the exceptions of clutch assists will be disallowed.

16. Contact Details and Communication

  1. Should any questions arise, team managers, vice managers, drivers and other persons can contact the series administration using the e-mail address below. Responses to any questions about the regulations, team line-up changes or other inquiries will be sent within 24 hours of us receiving the original message.
    Series E-Mail Address:
  2. The series administration will also use a Discord server during events, but can also be contacted there at all other points. The permanent invite link to the Sports Car Open Discord can be found here:
    Series Discord:
  3. Some members of the series administration can also be contacted via private messages on the iRacing forum. A list of these series administration members can be found below.
    • Dominik Engel
    • Ronald Großmann
    • Maik Paluch
  4. The use of the text and voice chat during qualifying and race sessions is forbidden. While occasional and accidental violations will not have any negative consequences, repeated offences will lead to penalties, especially if the message is intended to call out or insult another participant or series administration member.
