About iRTSS

The iRacing Team Sprint Series (iRTSS) is Champion Motorsports' Wednesday-night North American sprint championship. Events are single-driver races with no driver changes, creating a different test from the multi-driver endurance format used in iRTES.

The Fall/Winter 2026–27 season begins November 4 and runs through April 14. The schedule features 21 championship races, with holiday breaks on November 25, December 23 and December 30.

Pro & AM Driver Classes

iRTSS will recognize two competition classes for the Fall/Winter championship: Pro and AM. The goal is to give drivers a meaningful competitive target while still keeping the entire field together within the same Wednesday-night series.

AM Eligibility 2,000 iRating or Below
Pro Classification 2,001 iRating or Above
AM Option May Elect to Race Pro
  • Drivers with an iRating of 2,000 or below are eligible to compete in the AM class.
  • Drivers with an iRating of 2,001 or above will automatically be classified as Pro.
  • An AM-eligible driver may elect to compete in Pro at their choice.
  • A Pro-classified driver may not elect to move down to AM.
  • CMS Admins reserve the right, based on observation and competitive judgment, to move a driver from either class to the other when the Admin Team believes the change is in the best interest of competition, balance, and the spirit of the league.
Class philosophy: iRating provides the starting point for classification, but CMS Admins retain final discretion so that Pro and AM remain fair, competitive, and consistent with the spirit of the series.

Race Night Schedule

Every race night — Eastern Time
  • 8:30 PM ET — Practice / race server opens
  • Drivers Meeting — Approximately five minutes before qualifying
  • 9:15 PM ET — Private qualifying
  • 9:30 PM ET — Green flag

Feature durations vary by venue from 45 to 70 minutes. Shorter races are used where a compact sprint emphasizes precision and intensity; longer races are reserved for marquee, high-speed, endurance-flavored or special-event venues where strategy and sustained execution add to the challenge.

Holiday off-weeks: Nov. 25, Dec. 23 and Dec. 30. These are not championship rounds and do not count as drops.

Official Tuesday Practice

CMS intends to continue the established Tuesday practice concept. Official practice will normally be held the night before each race, with extended server time so drivers can prepare together and verify race-night readiness. Exact details will be posted in each week's Discord briefing.

Three Championships — Three Different Challenges

The Fall/Winter season will produce three distinct championship competitions. Each serves a different purpose, and scoring in one does not replace or override scoring in the others.

Championship 1 iRTSS Driver Championship

The main individual championship, with drivers classified as Pro or AM. Best 15 of 21 results count.

Championship 2 iRTSS Team Championship

Teams score across the full iRTSS season using their best two driver results at each race.

Championship 3 iRTSS × iRTES Masters

A six-round individual crossover championship tied only to the shared iRTSS/iRTES race weeks. No drops.

Overall iRTSS Driver Championship — Six Drop Weeks

For the full 21-race iRTSS championship, a driver's best 15 race scores will count toward the final standings. The lowest six event scores are dropped automatically at season end.

Why six drops? A 21-race Wednesday season is long. Counting the best 15 rounds still requires sustained participation across roughly 70% of the championship, while giving competitors enough flexibility for work travel, family obligations, illness, vacations and the occasional bad night. Drivers are free to compete in all 21 rounds; doing so simply gives them more opportunities to replace a weak score with a stronger one.

The event score used for drop calculations is the driver's final iRTSS score after normal finishing points, safety incentives and any applicable race penalties have been applied.

iRTSS Team Championship

In addition to the individual driver championship, iRTSS will also crown a Team Champion over the full Fall/Winter season.

  • A team must consist of at least two entered drivers/cars.
  • There is no maximum team size; organizations may enter as many drivers/cars under one team identity as they wish.
  • At each iRTSS race, only the team's two highest-scoring driver results will count toward that team's championship total.
  • Additional team drivers may still race and score normally in the individual championship, but only the best two event scores are added to the team total for that round.
  • The Team Championship scores all 21 iRTSS championship races. The six individual-driver drop rounds do not apply to team scoring.
  • The Team Championship is completely separate from the iRTSS × iRTES Masters Championship. Masters remains an individual-driver competition based only on the six shared crossover events.
Simple team scoring example: If four drivers from the same team finish an event with final iRTSS scores of 39, 34, 28 and 22 points, the team receives 73 points for that round — the best two results, 39 + 34.

iRTSS × iRTES Masters Championship

Sprint on Wednesday. Endure on Sunday. Master both.

Six iRTSS race weeks use the same venue as the iRTES feature that follows later that week. Those paired events form a separate six-round Masters Championship for drivers competing across both sister series.

No Drops in the Masters Championship

All six Masters rounds count. There are no drop weeks, no best-of formula and no discarded results in the combined championship. A driver trying to win the Masters title will want to participate in as many of the six crossover weeks — and in both halves of each week — as possible.

  • The iRTSS race still scores normally toward the full iRTSS championship.
  • The iRTES feature still scores normally toward the iRTES team championship.
  • For the Masters standings, the driver's normal iRTSS points from Wednesday are combined with the iRTES team points earned by the car the driver actually competes in on Sunday.
  • If a driver misses the Wednesday sprint, that driver earns no iRTSS component for that Masters round.
  • If a driver does not participate in the paired iRTES feature, that driver earns no iRTES component for that Masters round.
  • All six combined round totals remain in the standings.

Masters Championship Prize

The inaugural Masters Champion will receive a special CMS championship trophy plus a one-year extension of their iRacing membership, paid by Champion Motorsports.

The award is intended to recognize the driver who demonstrates the most complete racecraft across CMS' sprint and endurance environments over the full six-round crossover championship.

Realistic Weather & Race Conditions

iRTSS will use realistic weather throughout the Fall/Winter season. Conditions will be chosen to reflect the venue, time of year and character of the event rather than forcing every Wednesday night to run under the same dry-weather template.

Masters crossover weeks: For the six iRTSS × iRTES crossover rounds, the Wednesday iRTSS event will use weather aligned with the published iRTES race weather for that same circuit and race week. The goal is to make the sprint and endurance events feel like two parts of one shared CMS race week.

For the remaining iRTSS rounds, CMS Admins will select a realistic mix of dry and wet events across the season. Not every race will feature rain, and wet conditions will be used when they make sense for the circuit and season. Event weather details will be communicated in advance through the normal race briefing process.

Championship Points

iRTSS uses the same base finishing-points table as iRTES for consistency between the sister series.

Rules and Regulations

iRTSS follows the CMS General Competition Rules together with the iRacing Sporting Code. Drivers are expected to understand and follow both.

  • Each event will define an Orange Zone in the drivers briefing. Incidents in that zone are reviewed with heightened scrutiny and can receive stronger penalties.
  • Post-race penalties that must be served at a future race are the responsibility of the penalized driver. They must be served within the first three laps of that driver's next iRTSS race and may not be combined with a normal pit-box service stop.
  • CMS track-limit rules remain in effect, with iRacing's valid-surface definitions recognized where the simulator explicitly permits additional paved areas.

Drivers involved in an incident are encouraged to speak privately with one another first. If a formal review is still required, an Incident Review Request may be submitted through the CMS Race Review Committee process during the published post-race submission window.
