How to Increase Strength of Field in Iracing

Resolve how to increase strength of field in iRacing fast. Clear steps for iRacing drivers to fix weak matchups, improve field quality and race competitiveness.

If you want to know how to increase strength of field in iracing, the short answer is: you can’t change the math — you change the entrants. Strength of field (SoF) is driven by the ratings and number of drivers in the session, so attract higher-rated racers or enter higher splits to raise it. This guide shows exactly how.

Quick Answer

Strength of field is calculated from the ratings of the drivers in a session. To increase it, host or join events that attract higher iRating drivers: pick popular combos, schedule at peak times, invite strong drivers, or enter official/leagues where top splits live.

What’s really going on

iRacing’s “strength of field” reflects how strong the other drivers are in a session. It’s mainly influenced by iRating (your competitive rating) and how many high-rated drivers join. Strength of field affects ranking and the weight of iRating changes from a race. You can’t flip a switch in the menu to raise SoF — it changes only when better drivers show up.

Quick definitions:

  • iRating: a number that measures how competitive you are on iRacing.
  • SR (Safety Rating): shows how cleanly you race (fewer incidents).

Step-by-step fix

  1. Pick the right combo: Choose cars and tracks that attract serious drivers (popular GT, prototype, or top-oval combos). Less niche = more entrants.
  2. Run at peak times: Schedule events during evenings or weekends when more skilled drivers are online in your region.
  3. Publicize the event: Post in iRacing forums, Discord channels, Reddit, and leagues. Clear title, time (with timezone), and a link to the host/session help.
  4. Invite targeted drivers: For hosted/private races, invite friends or known high iRating racers directly or give a password to a competitive group.
  5. Use league/official formats: Sanctioned races and established leagues often draw stronger fields. Join or create a league with a roster of high-rated drivers.
  6. Improve your own entry: If you want better matchups when you join public races, increase your iRating by racing clean and performing well so you get placed into higher splits.

Extra Tips / Checklist

  • Use popular tracks (Spa, COTA, Monza, Daytona) — these attract more drivers.
  • Advertise with clear session settings (fixed setup vs open setup), race length, and rules to set expectations.
  • Offer small incentives (grid order, prize, or points in a league) to encourage serious drivers.
  • Don’t rely on AI — AI opponents don’t affect SoF.
  • If you’re trying to get into split 1, use practice and time trials to bump your iRating slightly before official race day.

FAQs

Q: Can I set a minimum iRating in a hosted session? A: No. iRacing doesn’t provide a host option to enforce minimum iRating. Use private/password invites to control entrants.

Q: Does SoF affect my iRating gains? A: Yes. Racing a higher SoF increases the amount of iRating you can gain or lose — stronger fields make rating changes more meaningful.

Q: Where do I see strength of field? A: SoF shows on the results page and in session info for hosted and official events.

Q: Will more entrants always increase SoF? A: Only if those entrants have higher ratings. Large fields of low-rated drivers won’t raise SoF much.

Wrap-Up

You can’t alter the SoF number directly — you raise it by getting better drivers into the session. Pick popular combos, run at busy times, advertise, and invite strong racers. Try one event using these steps and measure the SoF change on the results screen.
