With the introduction of Assetto Corsa Competizione into the sim racing world and months of testing completed, we’re proud to announce our Monday Night GT3 Series 3!

Assetto Corsa Competizione


Our ACC series has seen great success since our first season; with significant growth going into Season 2 and a thriving partnership with SRO America to bring the GT Rivals series to life, we’re proud to see how much our community has been able to offer. So first, thank you to all of our drivers, stewards, and admins whose dedication to the series has made all of this possible!

Now, onto what everyone has been waiting for!

CMS ACC GT3 Season 3

Our latest season expands upon what we’ve learned through all of our previous work and looks to further enhance the racing experience for everyone. Teams, success ballast, and reworked event formats make their way into our series, focusing on bringing the racing even closer while allowing drivers to work on improving each other’s skills and knowledge. On top of this, we’re branching out into new territory with a special event centered around driver swaps! Details can be found below.

We’re excited to begin and hope you all are as well!

To sign up, you can register here.

To determine your Driver Rating and Classification, you can find the following server:

CMS ACC Special Event


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

Driver Classes

Driver classes are determined by the performance of a driver through pre-season testing and over the course of the season itself.

Three classes are available:

  • AM – Those towards the back of the pack
  • 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 single lap turned on the qualifying server. The laptimes are pooled and compared against one another to determine where a driver stacks up against the rest of the field, resulting in a single number for their Driver Rating.

The classes are scored as such:

  • 0-60: AM Class
  • 60-80: Silver Class
  • 80-100: Pro Class

Drivers who recently joined and do not have a prior record must run on the qualifying server in order to receive a rating. Drivers who were present in the previous season will have their previous Driver Rating determine their Class until a result is given on the qualifying server.

Race Points System

Endurance Format

Position Points
1st 50 pts
2nd 45 pts
3rd 40 pts
4th 36 pts
5th 33 pts
6th 30 pts
7th 27 pts
8th 24 pts
9th 21 pts
10th 19 pts
11th 17 pts
12th 15 pts
13th 13 pts
14th 11 pts
15th 10 pts
16th 9 pts
17th 8 pts
18th 7 pts
19th 6 pts
20th 5 pts
21st 4 pts
22nd 3 pts
23rd 2 pts
24th and below 1 pt

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

  • AM Championship – AM drivers are scored independently of the Silver and Pro Classes
  • Silver Championship – Silver drivers are scored independently of the AM and 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
  • Fastest Lap: The driver who sets the fastest lap in their class during the race will be awarded 1 bonus points

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 extra bonus points are only awarded to the top driver in their class, and only at the end of the season.

Drop Rounds

Each driver is required to take two drop rounds during the season, where their worst results are dropped from the championship; however, any round in which you serve a penalty (not receive) cannot be nominated as your drop round.

Note: Drop rounds are handled in the same fashion for teams! The two worst combined results from a team will be dropped from the season, however, if either driver serves a penalty in a race, that race cannot be counted as a drop round.


Drivers may team up to form teams of two; however, certain conditions must be met to form a team

Drivers must be using the same Make, Model and Year of car

Only the following combinations are allowed:

  • Pro-Silver
  • Pro-AM
  • Silver-Silver
  • Silver-AM
  • AM-AM

Note that these classifications are determined by your Driver Rating. If you do not have a Driver Rating yet, you must run on our qualifying server in order to have an initial rating applied before applying for a team.

Success Ballast

Position Ballast
1st 50kg
2nd 45kg
3rd 40kg
4th 35kg
5th 30kg
6th 25kg
7th 20kg
8th 15kg
9th 10kg
10th 5kg
11th and below No ballast applied
  • Drivers who place in the top 10 are to be given a ballast based on their finishing position.
  • Drivers who carry an existing ballast and finish below the position that matches their current ballast will have 5kg removed. So for example, a driver with 50kg finishing 5th will carry 45kg into the next round.
  • If a driver earns consecutive wins, then an additional 10kg will be added per win, starting with the second win (first win nets no additional penalty beyond the normal 50kg)

Server Settings

  • The 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 pit boxes 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:

Formation Lap

We will be utilizing the Formation Lap Widget with ghosting enabled; any penalties received for being out of position/speeding during the formation lap will not be cleared.

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

Event Formats and Pitstop Procedures


  • Endurance races will have one qualifying session and one race session
  • The race session will be 60 minutes long
  • In some races, 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
  • Tires are mandatory for this pitstop, with fuel being optional; failure to take tires during the stop will result in disqualification.

Blue Flags

The ACC Chapter will be testing out blue flag rules different to the current CMS regulations. The rules are as follows:

  • Blue Flags are an advisory flag only
  • Passing a blue flagged driver is just like a normal pass, all rules regarding a proper pass applies
  • The moment the lapping car decides to go for an overtake on the blue-flagged car, the blue-flagged car must yield the position, and is not allowed to defend in any capacity. Racing room must be left by both parties.
  • 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 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 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.

Custom Skins

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

2) 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 will generally be left up to the drivers to submit a report form, 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 before joining the server on race day.

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