Coming off the popular 2019 NARS Winter Series, finding the right mix of cars and tracks and a format that would entice at least twenty of you to commit your Thursday evenings until Autumn was unusually difficult.

While Don and I had concocted the previous series that were mostly well-received, each previous series contained an inherent uniqueness that we could build series around. But this time we were going to run the same cars (by popular demand!) with the request of new tracks not run before (or not run for a while). Many of you weighed-in with excellent ideas about how we could best stir the contents into something familiar, similar, but still unique enough to hold your interest.

We looked at the open-wheeler options and decided those don’t fit the NARS charter. We also discussed running the LMP3 Nolda again but with some TC and ABS to make them friendlier to drive.

To complement the Studio 397 GT3 cars we ultimately decided on the EnduRacers Flat6 v5 Porsche Carrera Cup (PC) mod. They are incredibly fun to drive since they emulate the actual Porsche Cup Series held around the world, and there is a minimal amount of setup allowed and that should appeal to those who don’t have the time or interest in developing in-depth setups. While these Carreras are a notch down in performance from the “R” that is in the S397 GT3 package, the EnduRacers v5.00 options package made the difference in us not spec’ing the already included Porsche Carrera R as the second series.

For the format, there will be 8 tracks of 3 races each.

First will be the Porsche Carrera Cup cars in a 60-minute race with the grid determined by a 10-minute qualifying session. Then the following week, the first race is a 15-minute qualifier than a 45-minute “feature” race. Those two races will be run in the S397 GT3s.

We are going to bring back the Group A and Group B drivers championships that proved to be successful in 2018. Any driver that won a race, finished on the podium 3 times in the NARS Winter Series – Sprint or Endurance – or is a known sim racing alien or semi sim racing alien will go into Group A competition. Everyone else will run in Group B.

Unlike last years Group A / B competition, drivers will not move from Group B to Group A. This will allow drivers to establish competitive rivalries throughout the Series and race against the same drivers in their group. The listing of drivers is anyone who raced in the 2019 NARS Winter Series. If you do not want to be listed, please send Don Fryman or me a PM requesting your name be removed. Otherwise, we will presume you are planning to join in at some point in the series. Any “new” driver that did not participate in the NARS Winter Series will be assigned Group A or Group B by Don and myself. If you do not think you are in the correct group (A or B), please send Don or me a PM.

With 8 tracks and 3 races each, we noodled how many drop races to include. Over that period, everyone is sure to miss a few events! What we settled on were 6 drops. That is 25% of the races and the same percent we used for Endurance in the Winter Series. So the best 18 results of 24 races are the determination for the Group A and Group B championships.

It sounds complicated but it isn’t. The structure is already built and ready to go. Any drivers not listed on the page are welcome to join the series. Just show up and we will add you to Group A or Group B.

There is no pre-registration for the series. Just show up, drive, and have fun!

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”.

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 DDS file will get uploaded properly. If everyone waits until race day, it may clog the server and necessitate that we disable custom skin uploading.

1) rFactor 2 system delegated penalties (all must be served, and are not in race admin control)

Read the CMS GCR here [LINK]

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 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 even think of using a WiFi connection. Only Ethernet cable connections permitted for events.
