D. All sessions will have dynamic weather.
E. Sun acceleration multiplier will be set to 1x (real time).

G. Autoclutch will be the only assist allowed.
§3.3 Practice
Practice sessions are to be treated with the same quality of procedure as a race. To that effect, drivers will be expected to follow the rules and regulations in practice as though it was a race session. Race Control reserves the right to penalize drivers who are disruptive or unsportsmanlike in practice sessions. Explicitly: “Trying a move” that results in a crash which could have been avoided may be considered for penalty, as it is a) disruptive to the other drivers session for any testing being done and b) promotes poor passing behaviors that are strongly discouraged in this league. Penalties that are issued by Race Control for incidents during a practice session, will be applied to the race that the practice session pertains to.
§3.4 Qualification
A. As soon as a car has left it’s stall, a car’s qualifying session will be concluded if a car has been towed back to the pits for any reason, including towing in the pit lane. Cars are allowed to be driven back to the pits and to take service. Cars may be reset if they are in their pit stall.
B. Groups are determined before the race. Car numbers to start in Group A are the lower half of the field in total Championship standings and all GT AMs. Group B are the upper half of the field in total Championship standings, excluding AMs. For the first race of the season and a potential Pre qualification, groups are setup AM and PRO/AM together as Group A. Group B is PRO solely.
§3.5 Race Start
A. All races will have a rolling start.
B. All cars will start in a big group together.
C. Once the pace car pulls into the pit lane, the pole sitter will control the field until the start of the race. He must maintain a consistent pace car speed until the starting zone. Increasing speed before the start to spread the grid or overly slowing while the grid is approaching the start zone can be cause for investigation by Race Control; advantage gained or incidents resulting from these actions may be penalized.
D. An “acceleration zone” for the start of each race is defined in each Drivers Briefing Document. The pole sitter is to ignore the iRacing green flag and must accelerate within the area of this zone.
E. Cars may not overtake other cars in their lane until the Start/Finish-Line and have to maintain in their sides grid corridor.
F. Cars starting from pit lane will be released by Race Control over the @RACECONTROL channel. Jump starts, defined for this circumstance by crossing the cones at the end of pit lane with any part of the vehicle at any speed, will result in a penalty.
§3.6 Classification
To be classified in a race, a car must have:
A. completed 75% of the laps completed by the winning car.
B. abide by the class driver restrictions.
§3.7 Restarts (SC)
A. At restarts drivers must maintain SC speed until they reach the starting zone.
B. Each car is only allowed to accelerate as soon as the car ahead accelerates.
C. Drivers are not allowed to overtake until the S/F line.
§4 On Track Conduct
§4.1 Rejoining Track surface
A. Drivers must use the F3 black box throughout the race or have a spotter available, especially when rejoining the racing surface from a spin, off track, or coming out of the pits. Unsafe rejoins can and will be penalized. A general guideline to a safe rejoin is to make sure your car is parallel to the racing surface prior to rejoining the racing surface. Cars that rejoin the track safely should not attempt to impede the progress of another car, and should maintain a predictable track position until they are up to race pace. It is the driver’s responsibility to control their car when re-entering the racing surface: losing control of the car in the attempt, if it causes an incident, will be considered the fault of the driver attempting to rejoin. Do not cut across the track. Remember you do have a reverse gear!
B. A car which is at race pace but is not fully within track limits must yield to cars on the racing surface when reentering the racing surface.
§4.2 Passing
A. It is the responsibility of both drivers to ensure safe passing.
B. When two cars are reasonably alongside each other, each must permit the other adequate racing room. More detail on how a move is treated can be found in The Driving Standard Guideline
C. Under normal racing conditions drivers are not allowed to exceed the racing surface to complete a pass.
D. Drivers who are shown blue flags do not have to yield immediately. Once the passing driver has initiated the pass, the driver being passed must aid in facilitating the pass. The rules above still apply.
§4.3 Pit lane
A. It is illegal to circumvent in any way the pit lane speed limit, including but not limited to not using the pit speed limiter and manipulating gears while traveling down pit lane. Any driver found at fault will be issued a Drive Through penalty for Pit-lane infringement.
B. When entering and exiting their pit stall, drivers have five seconds to travel to and from the fast lane. Any driver found at fault will be issued a Drive Through penalty for Pit-lane infringement.
C. Cars in fast lane have priority use over cars coming from pit stall. If any overlap has been reached by the car in fast lane, the car coming from pit stall has to yield.
§4.4 Towing
A. Any car that is not capable of returning to pits (e.g. due to too much damage) is required to tow back towards pit-lane.
B. Racecontrol is monitoring on track activities. In case a car is not able to continue driving, Racecontrol is going to throw either a caution or a FCY (depending on the situation).
C. As this is a single driver series, you are allowed to tow back to pit-road, without requesting a tow first. However, you are to use the /tow command after you towed back to pits immediately.
D. If a car is within the area of an cut-out inside the barriers, a so-called safe-space, Racecontrol won’t throw a caution in case of a tow-request.
E. There is no tow-back requirement in Qualification.
F. At race starts: In case any gridded car is not able to take on the parade lap (e.g. due to technical defects) they may tow immediately, without requesting a tow.
§4.5 Safety Car Procedure
A. As soon as a Safety Car has been deployed, the overall leader is asked to slow down to Safety Car Speed.
B. Every other driver is asked to catch up to the queue as fast as possible without crashing.
C. Once the queue is catched, we’ll start sorting the field per class individually, each for their respective class leader, in queue order.
D. Pit-entry is closed in the moment the Safety Car is deployed. It is only reopend by Racecontrol. You are to ignore iRacing ingame messages.
E. Once the first wave-by process is finished, Pit-lane will be opened for one lap only.
F. As pit-stops are finished, the field is sorted again as per §4.5 C.
G. In case a team enters a closed pit-lane to serve an emergency pit-stop, it will receive an End-of-Line penalty just before the race restarts.
I. As soon as each class leader is the first car behind the Safety Car inside the queue, Racecontrol is announcing “One lap to green”.
J. After the restart Racecontrol will clear black flags for all cars once.
§4.6 Full-Course-Yellow
A. When a Full-Course-Yellow (FCY) is deployed, all drivers have to drive with their pit-speed limiter activated.
B. The pit-speed-limiter may not be circumvented in any way as described in §4.3 A.
C. Before a FCY is deployed, Racecontrol is counting down 10 seconds to FCY via ingame voice-chat. By the time the countdown reaches 0, FCY is deployed and any driver needs to be at pit-speed-limiter speed.
D. A countdown of 30 seconds will be announced via ingame voice-chat, before the track is going back to green. As the countdown reaches 0, Racecontrol announces “Green Flag”. With this command only, you are allowed to go back to racing speed.
E. In case of an offense against above rules, a penalty will be imposed in accordance with the penalty catalogue.
F. Any overtaking under FCY condition is prohibited.
G. Pit-road remains open during a FCY.
§5 Race Control
§5.1 General
A. All race sessions will have RC staff available monitoring on track activity.
B. RC will hand out penalties to drivers who fail to drive in a clean, fair manner, who act recklessly, or otherwise affect the spirit of competition within the series.
C. Penalties for Sprint races will be postponed to after race. Penalties for Master & Endurance races may be handed out in-game, if they are not able to be served during the race, they will be postponed to an equivalent post-race penalty.
D. RC may remove drivers from the track if they feel that their speed/lap times are too slow, or if they pose a risk to other drivers due to their driving, car condition, internet connection or equipment condition. In this case, a driver will first be warned and given time to correct this. In the event the issue persists, the driver shall be ordered to pit the car until the issues are resolved (repairs, driver swap for a bad connection, etc.). If the issues persist, the car will be black flagged for the remainder of the race.
D. Barring exceptions, RC will not reverse automatic penalties issued by iRacing. These penalties must be served according to the set procedure by iRacing.
§5.2 Reporting an incident
A. A driver can only report an incident if his car was directly involved in the incident. RC may also report incidents. If a driver is abusing track limits, driving overly aggressive, etc. lap after lap, teams can still inform RC of the issue so it can be monitored.
B. All reports must be made using the /protest tag from the Racecontrol Bot on the Discord Server. Incidents reported in any other form are ignored.
E. Post-race incident reports must be submitted within an hour after the finish of the event.
§5.3 Review of incidents
A. Incidents of Sprint and Master Races are to be reviewed after the race.
A. When RC is actively reviewing an incident, the Race Control Decisions Sheet will show it as “Under Review”. During this time, teams may come to RC and discuss their entry’s side of the incident for consideration. You may also use the /rc command to submit your point of view in a written form.
B. RC will inform a team of a penalty in the team’s Discord channel. Penalties will also be posted to the Race Control Decisions Sheet.
C. Once a decision has been made by RC and a penalty has been issued, a penalty may only be appealed if a team presents new information previously unknown to RC and relevant to the investigation. If the penalty was incorrectly issued (for example, to the wrong car) teams must notify RC ASAP using the /rc command and the penalty will be cleared. Race Control has no method of undoing a penalty once it has been served by a team; please keep this in mind.
D. Any penalty not served during a race because the car was retired before the penalty could be served, may be assessed post-race or in the following race.
E. If any filed incident reports are left unresolved by RC by the end of the race or if any post-race incident reports are filed, the penalties will be converted to equivalent post-race time penalties.
F. In case a protest was handed against a teammember of a Racecontrol member, the final word in an incident is to be left for only non-teammembers of Racecontrol.
§5.4 Serving of penalties
A. For this series we are using Slow Zones to reflect penalties.
B. For slow zones, you have to drive through a specially marked area on track with pit-speed limiter activated. This area will be announced in the drivers briefing document to each round.
C. The Slow Zone for each track is supposed to equate for roughly 3 seconds of time loss, while driving through it.
D. Any penalty converted to post race will be directly converted into 3, 6 or 9 seconds, according to our penalty matrix. However to any of those penalties, we will add 2 seconds for compensation of de- and acceleration, so the total amount of penalty is 5, 10 & 15 seconds.
§6 Penalty Matrix
§6.1 General
The following is a non-exhaustive list of penalties and reasons for penalties that RC may issue. The penalty amounts and number of PP listed are suggestions; RC may decide to award a different penalty amount or number of PP for any reason. Adjustments to penalty values or PP may be a reflection of: the safety or awareness demonstrated by a driver; mitigating actions taken by a driver to resolve errors; the severity of the outcome of an incident; the sportsmanship demonstrated. Race Control may also issue orders to give back a position or warnings for any of the penalty categories.
| Category | Description | Example | Penalty Guideline | PP |
|---|---|---|---|---|
| 1.1 | Incorrect Car in session | DSQ | 0 | |
| 1.2 | Incorrect Team ID/Number in Session | 1x Slow Zone | 0 | |
| 1.3 | Non-Registered Driver | DSQ | 0 | |
| 1.4 | Irrelevant Protest | 3 Pos Penalty Post Race | 0 | |
| 1.5 | Failing to meet class ratings | GT3 AM is not Bronze ranked | 5 Pos Penalty Post Race | 0 |

| 4.1 | Unsportsmanlike Conduct | 3x SZ – DSQ | 3 | |
| 5.1 | Others | Any | 0-3 |
§6.2 Definition of the classification of penalty levels
A. Minor Contact Responsibility
Slightly negatively effects a drivers race, example causing another car to spin and lose considerable time – Total loss ~ 5s (1x Slow Zone)
B. Moderate Contact Responsibility
Moderately negatively effects a driver or multiple drivers race and gives noticeable damage to the effected cars, example causes a car to spin and gives them rear end damage that requires repair in the pits to fix or spins one car causing that car to uncontrollably spin into other drivers negatively effecting their race – Total loss of Minor + ~5 seconds (2x Slow Zone)
C. Major Contact Responsibility
Severely effects another drivers race or moderately effects multiple drivers race or gives heavy damage that requires significant time to repair “ex. meatball flag for effected car” due to negligent driving. – Total loss of Moderate + ~5 seconds (3x Slow Zone)
E. Possibility of Upscaling
If Racecontrol finds the accused driver guilty of overaggressive driving, a severe lack of situational awareness or gross incompetence, the penalties may be enhanced to a higher total time loss.
§6.3 Penalty Points
A. Every penalty given to a car will be accompanied by Penalty Points (PP). During every race PP will be tracked for every car.
B. Any car that exceeds a total of 12 PP during a single race will be disqualified from that race.
C. When an entry both scores championship points and did not receive any PP in a race, the entry’s total PP will reduce by three. Entries cannot go below zero PP.
D. Once an entry or driver exceeds a total of 12 PP, the entry will be suspended for one race. If/when the entry gets back onto the grid, they will start the next race with 6 penalty points.
E. Any driver who exceeds a total of 9 PP during a single race will be disqualified from that race.
