A & B Group Settings

To attempt to minimize frustration among the greatest number of drivers – and candidly sustain as much interest and participation as possible in the series – we are going to allow driving aids for those that choose to use them. Each driver should decide what they want to use, or not use. There are two unique settings for each Group.

  • Group A drivers can use traction control on 1 only and anti-lock brakes on 1 only.
  • Group B drivers can use traction control, anti-lock brakes, auto-shifting, and stability control on any setting.

The server is set to allow driving aids. Because rFactor2 cannot separate which cars are which class, drivers will need to set their car settings allowable to their group.

Should a Group A driver use driving aids beyond traction control on 1 and anti-lock brakes on 1, they will be penalized by one race spot for each offense when the results are checked post race at Example: A Group A driver uses traction control on 3 and stability control on 2. They would be penalized 4 spots in the race results and points.

LiveRacers Timing & Scoring

LiveRacers will be used to record the hotlaps and the race.

Race Communications

1) We will use the CMS Discord voice 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”. 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) Comms is required. Should a driver join the event server without being in the Discord channel, they will be sent 3 text prompts in rFactor 2 text chat to join the CMS Discord server. After the 3rd prompt, they will be removed from the race server by race control until they rejoin with Discord active and monitoring the race channel.

Custom Skins

1) Custom skin uploading is welcome and encouraged, but please log onto the server a couple of days before the race so your file will get uploaded properly. If everyone waits until race day, it may clog the server and necessitate that we disable custom skin uploading.

CMS General Competition Rules

Penalties can be applied one of 2 ways in the April 30th race:

1) rFactor 2 system delegated penalties. All must be served and are not controlled by the live admins. Most times, admins don’t even know rFactor2 AI has dispensed a penalty!

2) A post race IRR submitted by the driver for review using the General Competition Rules.

CMS Gentlemen’s Rules

Drivers are requested to consider the following if involved in an accident…

1) 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.

2) Should you crash-out another driver by your error, consider retiring yourself from the race out of respect for the competitor whose race you ended.

Additional Drivers Notes

1) Don’t Press ESC! If you do, your race is over and there is no way for race admins to get you back into the race.

2) Un DQ is available on the server. If a driver gets a DQ. DO NOT TOUCH ANY KEYS ESPECIALLY THE ESC KEY! An admin will see you are DQ’ed and will UNDQ you as soon as possible.

3) Important! If it is still early light turn your headlights on before moving out of the garage or rF2 will DQ you again!

4) Open setups, but we encourage everyone to share!

5) It is strongly advised drivers reboot their computer just before joining the server on race day.

6) Don’t use a WiFi connection. Only Ethernet cable connections are permitted for NARS racing events.
