Welcome to 2024 Season 2. This season we’ll be going with a combination we haven’t used for a couple of years: LMP2 and GT3 (multiclass). This is also our first season with iRacing’s Tempest weather system, so expect to see a mixture of dry and wet!

Signups are required again, even if you have signed up previously.

We race every Wednesday night, session opens @8:30pm Eastern. Practice sessions every Tuesday night @8:30pm Eastern

How to Participate

To register, click the button above and fill out the form!

When signing up, you have the option of choosing your car class (GT3 or LMP2). GT3s are generally easier to drive, while LMP2s are more suited to experienced drivers. However, that’s just some very loose advice! Feel free to pick whichever class you’ll have the most fun with.

Please request membership to the Champion Motorsports league in iRacing, if you are not already a member. Membership on the CMS Discord is also a requirement, as that is where we will send out race briefings and other important news.

There is no cost to race in this series, beyond of course your iRacing membership and any content you do not yet own. If you wish to support CMS, you can click the Donate button on the right sidebar! Running a league of this size has costs, so every little bit is greatly appreciated and helps us provide bigger and better things.

Race Details

Some details may be changed on a per-race basis. Please read the posted race briefing for the race carefully! Briefings are posted on Discord before each race.

  • Random track starting state
  • Tempest weather configuration on a per-event basis (check race briefing)
  • Race session date and time will be included in the briefing (and see the table, above)
  • We will use rolling starts this season. GT3s are to leave a 5-7 second gap to the back of the LMP2s.
  • Some rounds will use Open qualification, whereas others will be Private. Check the briefing.
  • Races this season will be either 60 or 75 minutes in length.
  • Drive-through penalties will be assessed automatically:
    • Every 17x for ~60-min races
    • Every 21x for ~75-min races
  • One fast repair available for each race.
  • Drivers meeting will be held just before qualifying, using iRacing voice chat. All drivers must have voice chat enabled/unmuted during this period.
  • Voice chat during the race must be kept to a minimum (emergency safety callouts only).
  • Come to the drivers’ lounge (🎧iRacing channel on Discord) after the race to hang out with some of your fellow racers. (Optional, but we don’t bite!)

Series Specifics

  • We will be running open setups. Please check out the #setup-sharing channel on Discord, or talk to your fellow drivers in #discussion-weds if you are new to setups or would simply prefer to have a good setup from someone else.

Points

Please consult the points table for details. You must complete 50% of your class race winner’s laps to earn points.

Drivers participating in the 50+ championship will receive points towards that as well. In other words, you can earn points towards the main championship, and the 50+ championship.

Rules and Regulations

We follow all league rules as specified in the General Competition Rules at CMS, as well as the iRacing Sporting Code. All members are expected to understand and follow these rules at all times.

  • Everyone must be aware of the Orange Zone (OZ) for each race, as published in the drivers’ briefing. Serious incidents that occur in the OZ will be reviewed, and the stewards will impose higher penalties for any driver found to be at fault for an incident in the OZ.
  • If the stewards give you a penalty (in between races), it is up to you to serve that penalty within the first three laps of your next race, without stopping in your stall for any reason. You will not receive a black flag in game.
  • To be considered within track limits (per the GCR) you must have at least one tire on the white line. However, iRacing defines additional areas around some corners as being within track limits. As long as you are within iRacing’s track limits, you will be considered to be on the racing surface if an IRR is submitted.

Should you be involved in an incident on track, we encourage you to talk to the other driver first. If you wish to escalate it to be reviewed by the stewards, even if it is an OZ incident, you can fill out an Incident Review Request (IRR). All IRRs must be submitted between 12 and 60 hours after the race. You must join the Race Review Committee (RRC) Discord to submit an IRR.

Series Administrators

Your iRacing Wednesday night administrators are:

  • Michael Parker – Team lead
  • Ryan Thompson – Support, Steward liaison.

Please don’t hesitate to contact us via DM if you have any questions or concerns.

Note that—by design—we have no say over penalties or other stewards’ decisions. If you have a question about a steward (IRR) ruling, please visit the CMS RRC Discord and click the #irr-follow-up channel, or contact the Chief Steward. Please do not discuss incidents in public channels.


This series has been created for one purpose only: fierce, friendly competition on the track with like-minded racers, providing a place for everyone to race and have a great time doing so. We are all friends, here.

While we have rules in place, we also don’t intend to add complication or pressure to perform on race night. We all started sim-racing from scratch, and regardless of your experience we want everyone to feel welcome here. So please, come in and make some friends and we’ll see you on the track!
