How to race the dirt late model in iRacing: Why it matters

Dirt late models in iRacing are some of the most rewarding race cars you can drive. They’re powerful, tail-happy, and incredibly sensitive to throttle control and track conditions. Learning them teaches core dirt skills you can apply to any dirt car:

  • Reading the track: moisture, slick patches, cushion, and the bottom berm
  • Controlling yaw (the car’s angle to the direction of travel)
  • Throttle steering and light brake use to rotate the car
  • Clean racecraft: slide jobs, crossovers, and restart discipline

iRacing offers three dirt late model classes:

  • Limited Late Model: least power, most forgiving—great for learning
  • Pro Late Model: crate-style horsepower, still friendly
  • Super Late Model: most power and most demanding throttle control

If you’re starting out, learn in the Limited or Pro before moving up.

Step-by-Step Guide: From practice to race pace

Follow this sequence to build speed the right way.

  1. Set up your session and controls
  • Use a solo Test or AI session first. Add AI at similar iRating later to practice traffic.
  • Controls:
    • Map brake bias up/down and steering ratio adjust (if available).
    • Calibrate pedals. If your throttle is twitchy, add a slight curve/smoothing to make the first 30–40% more controllable.
    • Steering: 540–620° rotation with a 14:1–16:1 ratio is a good start for late models.
    • Brake bias: start around 60% front, then adjust ±2% for feel. More rear helps rotation but can cause spins.
  1. Read the track before you push
  • Dark, shiny dirt = moisture = grip. Light, gray, or polished = slick.
  • Early sessions: bottom and middle are fast; later: top cushion or a thin strip of moisture becomes key.
  • The cushion (built-up dirt at the top) can be fast but bites back—approach gradually.
  1. Master the basic lap
  • Entry:
    • Lift early and roll out of the throttle smoothly.
    • Brush the brake just enough to set the nose (5–15% pressure), then trail off.
    • Enter straighter than you think; don’t flick the car in.
  • Middle:
    • Let the car rotate on a small maintenance throttle.
    • Aim for 10–20 degrees of yaw—enough to help it turn, not so much that the RR tire free-wheels.
  • Exit:
    • Squeeze throttle progressively. No stabs.
    • Keep the steering as straight as possible to reduce scrub and wheelspin.
    • If the rear steps out, breathe off the throttle before adding steering.
  1. Choose lines as the track evolves
  • Early (heavy track): run low, keep LF near the berm; diamond the corner (late apex) to exit straight.
  • Mid-run (starting to slick): search for thin moisture strips in the middle; be patient on throttle.
  • Late (slick with cushion): run the top. Enter a lane below the cushion, float up to it, and “lean” on it on exit. If you tag it too hard, you’ll climb the wall—build up slowly.
  1. Racecraft that keeps you in one piece
  • Starts/restarts:
    • Roll into the throttle smoothly; anticipate checks ahead.
    • Pick the lane that matches your comfort: bottom is safer; top can launch if the cushion is strong.
  • Passing:
    • Clean slider: commit early, lift at the apex so you don’t wash into the wall, and leave a lane on exit.
    • Expect crossovers—protect the inside on corner entry after you slide someone.
  • Traffic:
    • If you spin, lock the brakes. Let the field miss you.
    • If you’re off-pace, hold your line and be predictable; faster drivers will work around you.
  1. Build consistency before chasing a setup
  • Aim for 10 laps within 0.2–0.3s.
  • Only then adjust brake bias or steering ratio to fine-tune feel.
  • In open setups, make small changes and test in 10-lap runs as the track slicks.

Drills that work

  • Throttle feather drill: run 20 laps at 7/10ths pace focusing on zero wheelspin noises off the corner. Lap time will stabilize when your exit is clean.
  • Entry marker drill: pick a board/cone; lift at the same mark for five laps in a row. Consistency first.
  • Cushion confidence drill: start one lane below the cushion. Each lap inch closer until you can “tap” it on exit without climbing it.

Key Things Beginners Should Know

  • Safety and comfort:
    • Solid rig and anchored pedals reduce fatigue and bad inputs.
    • Keep wrists straight; elbows slightly bent. Overgripping the wheel causes jerky steering.
    • Hydrate and take breaks—fatigue kills consistency.
  • Etiquette:
    • Use voice chat sparingly; type in warm-up if needed.
    • During a spin: lock brakes; don’t roll across the track.
    • Don’t send desperation sliders. If you’re unsure you’ll clear, don’t throw it.
  • Rules and incidents:
    • Off-tracks are rare on dirt, but contacts/spins add incident points that hurt Safety Rating.
    • Yield safely if you’re damaged or off pace.

Equipment, Gear, and Costs

What you need (and don’t):

  • iRacing subscription + dirt content: the Late Model(s) and a few dirt ovals you enjoy.
  • Wheel and pedals:
    • Load-cell brake helps with fine trail braking.
    • Wheelbase: 5–10 Nm is plenty for dirt; you don’t need a 20+ Nm unit.
    • Throttle pedal should be smooth and stable; add a light curve if you have a twitchy pedal.
  • Displays:
    • Single screen works. Triples or VR add awareness but aren’t required.
  • Optional software:
    • Spotter packs are nice, but iRacing’s default spotter is fine.
    • Basic overlays or delta timers help you verify consistency.

Money-savers

  • Start with the Limited or Pro Late Model and a couple of staple tracks (e.g., Eldora, Volusia, Fairbury). Expand later.
  • Fixed-setup official series let you focus on driving before you buy or build sets.

Expert Tips to Improve Faster

  • Drive the rear tire: imagine towing the car with the right-rear on exit. If it lights up, your hands got busy or you rushed the throttle.
  • Smooth hands, fast feet: aim for minimal steering corrections; make small, quick throttle adjustments instead.
  • Watch replays:
    • Chase cam: check yaw angle and how much countersteer you’re using.
    • Far chase: study your line versus the fastest guys.
  • Use AI to practice racecraft: rehearse clean sliders and crossovers before officials.
  • Don’t over-rotate: if you’re more than ~20–25° of yaw, you’re slow. Enter calmer or add a tick of front bias.
  • Brake bias is a rotation tool: more rear = more rotation on entry; too much rear = spins. Move it 1% at a time.
  • Steering ratio tweaks:
    • If you’re sawing at the wheel, try a slower ratio (16:1).
    • If the car feels sluggish, try 14:1.
  • Know when to move up a lane: if your lap time plateaus and you’re fighting wheelspin off the bottom, sample the middle or top for two laps. If it’s faster, commit.

Common Beginner Mistakes

  • Mashing the throttle on exit, then countersteering wildly. Fix: squeeze throttle; straighten the wheel first.
  • Chasing the cushion too early. Fix: build speed on the bottom/middle until you’re consistent, then move up.
  • Entering too sideways. Fix: lift earlier, trail the brake lightly, aim for a straighter entry.
  • Sawing at the wheel. Fix: slower ratio, lighter grip, and commit to a line.
  • Setup hunting before consistency. Fix: hit your marks; then adjust one change at a time.
  • Throwing late slide jobs. Fix: if you wouldn’t clear by halfway through the corner, wait.

FAQs

Q: Which dirt late model should I start with? A: The Limited or Pro Late Model. They’re more forgiving and teach throttle control without the Super’s power spike.

Q: What force feedback and steering settings work best? A: 540–620° rotation with a 14:1–16:1 ratio is a solid baseline. Avoid clipping; set max force so big bumps don’t saturate FFB.

Q: How do I know when to run the cushion? A: When the bottom polishes off and your exits start spinning. Test the top cautiously—enter a lane below it, float up, and “lean” on it at exit.

Q: Any quick setup advice for open races? A: Keep changes small. Start with a reputable baseline, adjust brake bias and steering ratio for comfort, and gear so you’re not banging the limiter. Test in 10–15 lap runs as the track slicks.

Q: How do I practice slide jobs safely? A: Use AI. Enter low, lift early, aim to be clear by the apex, and leave room on exit. Expect an immediate crossover—plan to protect the next corner.

Conclusion

You don’t need perfect gear or a magic setup to be fast in iRacing’s dirt late models. You need discipline: read the track, manage yaw, roll the throttle, and race with respect. Start in a practice or AI session, master the bottom, sample the middle and cushion, and only then jump into officials.

Your next step: run a 20-lap practice at a favorite track, hit consistent laps within 0.3 seconds, and save the replay. Study your yaw and exits, make one change, and repeat. That’s how you build real speed.
