2021 NARS Virtual Porsche GT3 Cup Asia Short Series



Since 1993, Porsche has been promoting and supporting one of the premier single-make racing challenges in the world. Having started with a single series, over the years it has evolved and grown into 3 tiers of racing with the most prestigious, known as the Porsche Supercup, part of the support program of the FIA Formula 1 World Championship.

The third tier is the Porsche GT3 Cup Challenge or Porsche GT3 Cup Trophy, which is a mixture of smaller series in Europe, the Middle East, the Americas as well as New Zealand, Australia, and many other regional venues.

Our races will evoke a little of the real-life PCC Asia series using the S397 911 GT3 Cup DLC and a selection of tracks from the region.

Race Format

Following the general form of the real-life races, each round will feature a qualifying session and then 2 standing start sprint races of approximately thirty minutes each as well as live weather. As in the case of the 2021 season, the Race 1 finishing order will be used for Race 2 with the top 10 finishers reversed.

Race Schedule

The 4 rounds are:

October  28 – Shanghai

November 4 – Zhuhai

November 11 – No Race (Remembrance Day)

November 25 – No Race (US Thanksgiving)

December 2 – Zhejiang

December 9 – Marina Bay

Car and Track Mods

Drivers wishing to race must be subscribed to the NARS Steam Workshop item at:

Don’t forget to also check the Workshop item for linked Steam content.

The car is the S397 Porsche 911 GT3 Cup DLC and may be purchased on the Steam Store:


Drivers Championship

There will be two classes of racing – PRO and AM as follows:

Both classes may use AUTO CLUTCH.

PRO: (intended for more experienced drivers): may not use any other driver aids.

AM: (intended for those new to racing, still working on their skillsets or finding that ‘finding the time’ for preparation is a struggle): may also use AUTOBLIP/LIFT as well as ABS and TC on LOW. NO other driving aids are permitted.

Settings will be verified post-event. A driver who has used aids in excess of those permitted for their class will be penalized 2 class positions in the race for each additional aid or level of aid used.

Choosing your Class

As this is a short series, there will be no ‘tailoring’ of the mod and so drivers will need to declare their PRO or AM status prior to their first race. Drivers failing to declare their status before racing will automatically be classed as PRO. There will be no changes in driver class during the series.

Drivers may join in the racing at any time during the series without penalty.

General Information

Open setups, but we encourage everyone to share!

Custom Liveries

The series will use the liveries provided and drivers are encouraged to paint their custom liveries. Templates are available in the /templates folder of your rFactor 2 install once the mod is purchased.

Drivers choosing to design a custom livery are also encouraged to use their NARS number. Custom livery loading will be through the use of loose skins and .mas files if the driver decides to paint more than just the car; please log onto the server a couple of days before the race so your file will get uploaded properly and avoid clogging the server on race day.

Pit Stop

There will be no mandatory pitstops.


  • We will use the latest retail build of rFactor 2.
  • The damage setting is 75%.
  • Crash Recovery is off. That means your car can fly off the track and land upside down. Drive carefully!
  • Driving View is open.
  • The weather will be live.
  • The server name will be “CMS PCCA Track Name”.
  • The practice server will be active 7 days before race day, with no password.
  • For the race, the server will be password protected and the password will be available on the CMS Discord NARS #PCCA-info channel prior to server reboot on race day.

Race Communications

  • We will use the CMS Discord rFactor 2 voice channel for race communications.
  • CMS Discord is available at https://discord.com/invite/4ckmjPX
  • The voice channel is only required to monitor race control during the event. You do not need a microphone if you do not want to speak.
  • 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/girl”.
  • Chatter during free practice is permitted and encouraged! For qualification and races, please be brief in your communication on Discord and talk only if absolutely necessary. One sentence then quiet is requested. No text chat AT ALL during qualification or race.
  • Abusive and/or profane in-game chat, Discord, or forum post language may lead to that driver receiving a sanction up to and including a ban from CMS.
  • 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.

Competition Rules and Stewarding

  • This series will conform to the CMS General Competition Rules that may be found on the CMS Discord Server. All drivers are expected to know the GCR and shall be required to abide by them.
  • There are no live stewards. A post-race Incident Review Request may be submitted for adjudication with any resultant penalties to be served in the next race competed by the driver(s) at fault. The IRR form may be found at https://cmsracing.com/incident-report/.
  • rFactor 2 system delegated penalties during races must be served. Race control will ONLY have the capability to clear penalties and driver DQ during practice on the race server and then AFTER qualification but before the race.

Connection Notes

  • Drivers are strongly advised to reboot their computers just before joining the server on race day.
  • Don’t use a WiFi connection. Only Ethernet cable connections are permitted for NARS events.
