As with the 2021 iRTES, the format for this 2-3 driver team endurance series will be loosely based on the World Endurance Championship (WEC) structure. The series will offer podium trophies and multiple prize opportunities for competitors.

  • Starting in January 2022, the six-race series will offer two events per month.
  • The series will be a multi-class competition with LMP2 and GT3 classes.
  • There will be a separate scoring championship for each class.
  • Each event is 3 to 6 hours in length at iconic racing venues.
  • The series will be time-friendly to the Americas and Europe.
  • The goal is to offer a series that allows everyone to participate!

Support Series

In addition to the iRTES, there will be a support series, the iRTES CMS Cup that runs just prior to each iRTES Endurance round. Details are still being determined, but the following information has been decided:

  • Single driver races (not team-based)
  • The car will be the new iRacing Porsche 911 GT3 Cup 992
  • Fixed, custom setups
  • Same track venues as the iRTES.
  • Race lengths of 30 minutes.
  • All CMS drivers are eligible to join. No entry fee, no pre-registration.
  • The support series will not be broadcast, so drivers are encouraged to use Trading Paints.

Your team will need to make the entry payment no later than December 30th, 2021.

The iRTES CMS Cup Series does not have an entry fee. All CMS members are welcome to join this support series to the iRTES Endurance Series.

iRacing Teams

  • Teams will use the iRacing Team criteria.
  • Registered teams are the only drivers eligible to drive.
  • Driver swaps will use the iRacing “fair share” criteria for team driving.
  • A team must maintain its drivers for the duration of the series.
  • Teams can register up to 6 drivers per entry, but only 3 of the 6 drivers can drive in a race event.
  • Any 3 driver combination of the 6 registered can drive in an event, but the first two drivers that connect to the server will be locked-in to drive for the race. This is built into iRacing. It is not something CMS admins can edit.
  • If additional drivers are required for an entry to make a race, a new entry must be registered. Points from the original entry will not carry over to the new entry.
  • “New” team registrations will not recover existing series points from an “old” team.
  • The Series will have a maximum number of 50 teams, of which 30 are GT3 and 20 are LMP2.
  • After 50 entrants, Teams will join a waiting list based on first come, first served.


  • A reminder that in iRacing, only the car you drive is required to be purchased, not all the cars running in the series!
  • Teams must drive the same car throughout the entire season.
  • If a team chooses to change to a different car during the season, the team will need to re-register as a “new” entry, and all points scored in the preceding series events are forfeited.

Events & Practice Schedule

  • Each event will have a 4-hour open practice session, a 30-minute test race, and the race itself.
  • Participation is optional for the open practices and test races, but for those that can attend it will be a good opportunity to test your setup, strategy, and tactics.

  • There will be a 45-minute practice session before qualifying.


  • Drivers have 15 minutes (except Le Mans which will have 20-minute qualifying) to complete up to 3 timed laps during the qualifying session, the quickest of which will be used to determine the qualifying position for the race.
  • The driver that sets the qualifying time must also start the race.

Warmup Lap / Race Start

  • Rolling start.
  • No tire warming.
  • Classes are grouped.
  • The race starts on the iRacing green.
  • The polesitter for each class determines the class speed on the warmup lap.

Orange Zone

The start of any race and the first lap is the most likely time for incidents to occur. To control avoidable contacts, first corner pile-ups, or aggressive driving habits, there will be a designated “Orange Zone” (OZ), inside which drivers are expected to be more cautious, to avoid high-consequence incidents and the potential for ending someone’s race. The OZ will change from track to track and will be announced in the CMS Discord “Sundays – iRacing Team Series” category.

Safety Car

A safety car will be used at the race admins’ discretion when warranted.

General Information & Settings

  • The iRTES Series will run open setups, but we encourage everyone to share!
  • Fuel capacity in each class is 100%.
  • The weather will be variable.
  • Track state: Rubber will progress between sessions. Marbles will be cleaned after each session.
  • One Fast Repair.
  • No drop races. All 6 events count towards the championship.
  • Points will be awarded after each event to entrants based on their finish within their own class.
  • Only use an Ethernet cable connection. Do not use a WiFi connection. If your team’s connection is unstable in iRacing, you will be first asked to park your car in the pits to see if it stabilizes. If the problem continues, you will be asked to disconnect from the race, reboot your computer and try to reconnect. If your team still has a bad connection, as a very last resort the team will be removed from the event.

Custom Livery

  • All teams are required to use Trading Paints custom livery.
  • There will be a series designated template for each car that will be “stamped” by the race server.
  • Teams must use the correct, designated template for their car or they will be disqualified for that event.
  • Submitted skins must comply with iRacing’s Custom Paint Policy.


1) Information will be dispersed primarily on the CMS Discord server in the CMS Team Endurance Series category.

2) While on the race server, voice comms will be exclusive to the iRacing radio function. No race comms during the event will be transmitted on Discord.

3) Immediately following the race, the podiums for LMP2 and GT should join the Discord channel #winner-interviews located on the CMS Discord server in the CMS Team Endurance Series category for their winner’s interviews by the broadcasting team.

4) Set your microphone to “push to talk”. If that just doesn’t work for you, PLEASE set the voice-activated audio level up considerably so your coughing, wheezing or sim controller grinding isn’t “shared” with everyone else.

5) Abusive and/or profane in-game chat may lead to that team receiving probation, suspension, or ban from the league.

6) Do not “call out” or argue with a competitor or race control. If you persist after being warned, the team microphones will be disabled in iRacing during the event.

7) Teams are encouraged to use their team radio within iRacing.

8) A penalty applied by iRacing AI in avoiding a crash is eligible for review by race control.

To have race control review for an errant penalty, the driver of the team car should call out to race control:

  • Their car number.
  • Reason for the penalty.
  • A one-sentence description of what happened.

Race control will respond with “car number 123, reviewing”.

After review, the driver will see on their screen that the penalty has been removed.

Incident Count

  • Teams will receive a drive-thru penalty after 25 incident points.
  • Teams will be disqualified after 50 incident points.


1) Penalties will be applied by the in-race iRacing AI function.

2) A race controller will be present during each event, but will not intervene during an event except:

  • to clear an errant penalty (specifically defined below).
  • to remove a team from competition in the case of connection lag, reckless, and/or retaliatory driving.
  • a violation of race comms rules.

3) All penalties must be served and cleared by the iRacing AI. Remember race control does not see penalties from iRacing AI, so if a driver asks, “why did I get a penalty?” race control will not be able to advise, only that a penalty was issued.

4) Make sure you read iRacing’s FIRST Sporting Code section on how penalties are applied and how to clear penalties.

5) CMS Gentlemen’s Rule – Should you turn-around or damage another driver by your error, consider pulling off track in a safe location and waiting for the other driver to proceed in the race.” This is an elective decision, but penalties will be significantly reduced if adhered to.


Teams are expected to have their drivers available on race day, but if an emergency happens and only one driver can attend, they are welcome to run the event but they may be DQ’ed before the end of the event so their status is properly displayed on the broadcast results at the end of the race.

Post Race Incident Race Report (IRR)

  • Teams have 24 hours to complete and submit the IRRs from the time the official race replay is posted.
  • Only the official replay may be used for IRR submission.
  • The official race replay will be posted immediately after each event.
  • Download the replay file from the CMS Team Endurance Series Discord category.
  • Download the CMS IRR form here.
  • Penalties will be applied to the results of the current race.
  • Results for each race are not final until all IRRs have been processed.
  • The decision of the post-race IRR review group is final.
