With the introduction of Assetto Corsa Competizione into the sim racing world and months of testing completed, we’re proud to introduce our Monday Night ACC Series! Being a GT3-focused title, we’re taking full advantage of the tools they’ve given to us. The series is run to mirror the real-life Blancpain GT3 series, including all available tracks, driver classes, and more.

With Season 1 complete and the holiday season upon us, we’d first like to thank everyone who participated in our first ACC Season! Results from Season 1 can be found here.

We’re striving to expand upon our successful first season with Season 2 of our GT3 series, with expanded race formats, revised points system and updated Driver Ratings! Along with this, we’re bringing the single-make Porsche Cup Car Series to the table, which mirrors the GT3 season tracklist and event format.

Registration for each series is required and open; a link for each can be found below. Of course, participation in either is optional, and one will not influence the other in any way.

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.

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 simracing or a seasoned veteran, there’s great racing to be had here!

Special Events

Currently, there is one upcoming special events planned:

CMS ACC Open Practice and Shared Test Race

  • Starting at 9:00 AM EST, January 6th, 2020
  • Track: Monza
  • Car: Free selection, no restrictions
  • Sessions:

– 720 minute Practice
– 30 minute Qualifying
– 60 minute Race

  • Mandatory Pitstop for fuel and tires
  • No registration required


All cars from either the 2018 or 2019 season will be allowed in our GT3 Championship.

Mid-season car swaps will be restricted to specific points throughout the season to keep things organized. The frequency of these points will depend on the length of the season. The cost of switching cars mid-season will be ALL points accumulated up to that point.

To request a car swap during a season, please reach out to a series admin with the requested car so proper adjustments can be made server-side.

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 unless a mid-season swap is requested.

Driver Classes

Driver classes are determined by the performance of a driver through pre-season testing and throughout the season itself. Two classes are available:

  • Silver – Those who make up the lower portion of the field, and may struggle with outright pace or consistency.
  • Pro – The fastest drivers, and the measuring stick we use to evaluate all other drivers’ pace.

Drivers are evaluated based on their best qualifying lap(s), best race lap(s), and average race lap times. These results are used to produce a ‘Driver Rating’, which is used to determine driver class. The classes are scored as such:

  • 0-70: Silver Class
  • 70-100: Pro Class

Divers who don’t have many races to their names will be given some leniency to account for any incidents during the race that may negatively impact their rating. The rating for each driver can be viewed in the Season Results, linked above in the Information section.

Drivers who recently joined and do not have a prior record will be given the AM tag until a reasonable rating can be given. Drivers who were present in the previous season will have their previous Driver Rating determine their Class.

12th 7.5 points 24th & below 0.5 point

Drivers must complete 50% race distance of the leader’s final lap count to score points.

If the drivers need to be split across multiple servers, they will be split by Driver Class. To determine the scoring in the overall championship, each drivers’ Total Time from the relevant race sessions will be compared and sorted overall; the Overall Championship Scoring will be taken from this result.

End of Season Class 1st place bonus – 3 Points (goes towards the Overall points system)

Each class will be scored independently, with the season hosting a total of two championships:

  • Silver Championship – Silver drivers are scored independently of the Pro Class
  • Overall Championship – All drivers are scored here in the form of an overall result for the season. As it’s expected that PRO drivers are expected to be fighting at the front, they are not scored in their own class.

Bonus Points

At the end of each race, points will be awarded to drivers that have excelled in a particular category. Available bonus points are:

  • Pole Position: The fastest qualifier in each class will be awarded 1 bonus point (2 if only one qualifying session is run)
  • Fastest Lap: The driver who sets the fastest lap in their class during the race will be awarded 2 bonus points (1 during a sprint race)
  • Best Consistency: The driver with the highest Consistency Rating in their class will be awarded 2 bonus points (1 during a sprint race)

At the end of the season, the person who finishes first in their respective class will receive 3 additional bonus points towards the Overall Championship race points standings.

For example, let’s say you are in the Silver class, and we have a 10 race season. You finish 8th in each race, you would get 24 points each race so you get 240 points total in the Overall Championship race standings at the end of the season. You then finish 1st in the Silver Class Championship at the end of the season, so you receive an additional 3 points towards your Overall Championship race standings. So now you would have 243 points and potentially can beat another driver ahead of you in overall scoring. The 3 bonus points are only awarded to the top driver in their class, and only at the end of the season.

Server Settings

  • Server will be using a password and will NOT rely on the ACC rating system
  • The server capacity is determined by the number of available pitboxes at a given circuit; if more server space is needed, the backup server will be utilized and drivers split by class.
  • 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

Starts & Other Procedures

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

  • At the beginning of the formation lap, drivers are to proceed single file around the lap, while not exceeding 145 km/h (90 mp/h)
  • Please allow a reasonable amount of time for cars ahead to get away from the grid at the start; as it’s a full formation lap there will be plenty of time to catch up to the field.
  • In the case where a car does not leave the grid in a reasonable amount of time, cars behind are allowed to overtake in order to remain close to the rest of the field.
  • Cars that stalled on the grid can overtake to regain their starting position, however if any of these overtakes are performed in an unsafe manner, please report it.
  • If you are unfairly overtaken during the formation lap, please report it.
  • At the point where ACC tells drivers to form up in double file towards the end of the formation lap, leaders are expected to reduce the pace to a maximum of 95 km/h (60 mp/h) to bunch up the field; please make sure to form up on the correct side of the grid as well.
  • The field will proceed in double file until the green flags are waved, at which point the race begins.
  • Tire warming through weaving and heavy braking is forbidden; however, drivers are allowed to ride their brakes to generate heat instead.

Orange Zones

1) Each race will use an orange zone, a zone where drivers are required to be extremely cautious when performing an overtake or defending

2) Orange Zones will be posted within the specific event thread on Discord

Event Formats & Pitstop Procedures


  • Sprint races will have two qualifying sessions and two race sessions.
  • The race sessions will be 30 minutes long each.
  • The results from Q1 will apply to R1, and the results from Q2 to R2.
  • We will use the formation lap on R2 to sort the field to match the order in Q2.
  • There will be no mandatory pitstop in the Sprint format, and refueling during the race will be forbidden.


  • Endurance races will have one qualifying session and one race session.
  • The race session will be 55 minutes long.
  • There will be one mandatory pitstop during the race, which must be served within the 20 minute pit window in the middle of the race.
  • Both tires and fuel are mandatory for this pitstop; failure to take one or both during the stop will result in a disqualification.

Blue Flags

  • During a blue flag situation, the car behind is responsible for performing the overtake; cars that are about to be lapped are NOT expected to move off the racing line. The car being lapped must act in a safe, predictable manner. That being said, overtaking cars should take into consideration the potential difference in pace and skill between themselves and the lapped driver, and should act accordingly.
  • The overtaking car should signal to the car ahead when they plan to overtake (flashing lights, signals, etc.), then move to a position to overtake.
  • If a driver that is a lap ahead feels they are being unfairly and significantly held up by a lapped car, please report it. Please reserve this only for extreme cases, as this can vary widely with each drivers’ comfort level at certain areas of each track.

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 is available here.

3) Comms is 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 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 complete an Incident Report.

Custom Skins

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

2) As car numbers are currently restricted in ACC to disallow any number beginning with a 0 (00, 03, etc.), we will be referring to the CMS Master Number List as a priority; all drivers not on the list will be able to claim their number on a “first come, first serve” policy in the ACC Discord channel.

NOTE: The Lexus will NOT support custom liveries, however custom driver numbers will work.

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.

2) Upheld Incident Report via Race Review Team

      • Incidents that occur within the Orange Zone during a race will have a report submitted by a series admin to have the incident reviewed
      • Incidents that occur outside of the Orange Zone 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.

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) No WiFi connections. Only Ethernet cable connections permitted for events.
