With the introduction of Assetto Corsa Competizione into the sim racing world and months of testing completed, we’re proud to announce our next Monday Night Series!

Season 9 – Assetto Corsa Competizione

ACC Season 8


Season 8 is now past, with one of our strongest showings in the ACC chapter in a long while; first and foremost, thank you to all drivers who took part in the season with us! It’s your attendance and feedback that keeps the admin team pushing each season, and we hope Season 9 will bring the best yet!

Speaking of Season 9, it’s time to revisit an old enemy: GT3 and GT4 multiclass racing! Returning for the primary split in S9, the season will feature up to 25 of each class duking it out on the same bit of tarmac across 9 tracks. This will be a critical test of each driver’s patience, traffic management, and strategy, not to mention a revitalized format lineup to further shake up each week.

Alongside this, our supplemental class remains as a single-make series for those looking to go head to head in identical machinery, while making for a perfect development ground for drivers new to CMS or ACC!

We hope everyone is looking forward to this season, and wish good luck to you all!

Driver Registration

You can sign up for our series at The Sim Grid by joining our community here: https://www.thesimgrid.com/hosts/cmsracing

Discord is required for those wishing to race with us; before every event, we hold a pre-race discussion with key details specific to the event. You can join us here at https://discord.gg/4ckmjPX

If you have any questions you can feel free to ask a question in the ACC League channel on our discord. Drivers of any skill level are welcome; whether you’re new to sim racing or a seasoned veteran, there’s great racing to be had here!


All cars will be allowed in their respective class unless otherwise stated.

The car that the driver(s) in question used during the first race is the car they will be forced to use for the remainder of the season. There will be no mid-season swaps allowed.

Deciding on a Split – What’s the Best Fit?

With Season 9 being multiclass, the sole recommendation we can offer is to run in a car you’re most familiar with, both driving within and occasionally beyond the limits. Multiclass will be tense with a strong emphasis on car control due to the pace differences of the cars, so having one that you’re fully comfortable in will prove a great asset in the championship.

Alongside this, we of course have the supplemental single-make series for those wanting to run in equal machinery. Skill level in all classes will be fairly diverse, though for new members we highly recommend the single-make split to have the strongest opportunity to learn from long-term members in identical cars.

Should I Run on the Qualifying Server?

While not mandatory, it’s highly recommended! Details for the server can be found here: https://www.thesimgrid.com/championships/429

But to put things simply, all we’d like is for any interested driver to turn one timed lap that they’re happy with. This time gives you a reasonable baseline representation of where you stand in our community in terms of one-lap pace, and should give guidance as to which split may suit you best.

Series Schedule

Series 9

Event Schedule

8:50 PM EST – Mandatory Pre-race talk in Discord
9:00 PM EST – Server Start
10:50 PM EST – Finish


The race starts will include a full formation lap; during this lap, the following regulations are expected:

  • We will be running a full free formation lap. During this lap, the lead car is expected to maintain a speed of 100km/h or 60 mp/h during single file, and a speed of 60 km/h or 37 mp/h during double file.
  • Drivers are expected to switch to double file at the start of the third sector. Note that double-file should be a true double file, not a staggered grid!


  • Qualifying format and length is determined via the event format being run.
  • Blue Flagged cars should not race cars that are on a flying lap.
  • Passing is allowed, it is expected to be done quickly, cleanly, and fairly.

Orange Zones

  • Each race will use an orange zone, a zone where drivers are required to be extremely cautious when performing an overtake or defending.
  • Orange Zones will be posted within the specific event thread on Discord.
  • Reported incidents that occur within the OZ will be handled more severely than normal, so please keep this in mind when racing!

Blue Flags

  • Blue Flags are advisory flags only.
  • It is expected that the slower car will maintain the normal racing line, and the lapping car is expected to make the pass cleanly.
  • The specifics of the blue flag rules can be found in the GCR: https://cmsracing.com/general-competition-rules/

Drop Rounds

For Season 9, no drop rounds will be available while we validate the scoring system. If all appears well, a manually calculated drop round will be factored in at the end of the season.

Server Settings

  • The server will be using a password and will NOT rely on the ACC rating system
  • Weather will always be set to dynamic; while we can influence the weather to a minor degree, we will not be guaranteeing any conditions for a particular event
  • Pitstop regulations will be shared with the relevant upcoming event and will be discussed during the pre-race meeting

Timing & Scoring

We will be using ACC’s results files from the server to keep track of all race results and timing.

Race Communications

1) We will use the Discord ACC channel for race communications.

2) CMS Discord information is available here.

3) Comms are required, but only to monitor race control during the event. You do not need a microphone if you do not want to speak.

4) If you have a microphone, please set it to “push to talk” or “toggle mute”. If that just doesn’t work for you, please set the voice-activated audio level up considerably so your coughing, wheezing or sim controls grinding isn’t “shared” with everyone else. Don’t be “that guy”.

5) A request to drivers to please be brief in your communication on Discord.

6) One sentence then quiet is requested. Abusive and/or profane in-game chat, Discord or forum post language or deliberate crash into a competitor’s car may lead to that driver receiving probation, suspension, or ban from the league.

7) During practice sessions, more open discussion is welcome, however during qualifying and the race please minimize communications to allow all drivers to focus.

Reporting an Incident

If you are involved in an incident of any sort during any session, please report it here. Please include which session and at what time in the session the incident took place, as well as a brief description of what occurred.

Custom Skins

1) Custom skins are allowed and encouraged; client-side liveries will work just fine.

2) Driver numbers can be requested via reaching out to a chapter admin; numbers operate on a first-come, first-serve basis!

CMS General Competition Rules

Penalties can be applied one of 2 ways:

1) ACC system delegated penalties

    • During qualifying and races, all penalties must be served, as there will not be an admin available to review during the session
    • During practice sessions, warnings and drive-throughs will be cleared upon request to prevent drivers from losing session time.
    • Note: The track limits used are the in-game track limits designated by ACC, however when in-game track limits fail to account for certain scenarios (such as off-track overtakes or wet conditions), the standard GCR will apply regarding the track limit, racing and limit abuse rules.

2) Upheld Incident Report via Race Review Team

    • Incidents that occur will generally be left up to the drivers to submit a report for unless a significant number (3 or more) drivers are involved in the incident.
    • Penalties assigned based on these reports will be applied in the appropriate session by a steward or admin at the next round the driver takes part in.

Read the CMS GCR here.

Additional Drivers Notes

1) We will attempt to clear any penalties a driver receives in practice, however no action will be taken during the race or qualifying.

2) Open setups are allowed, but we encourage everyone to share!

3) It is highly recommended drivers reboot their computer just prior to joining the server on race day.

4) Don’t even think of using a WiFi connection. Only Ethernet cable connections are permitted for events.
