EA Sports WRC: unstable under braking — what to change

What it feels like

Braking hard in a straight line the car moves around, the rear tries to come round or you lock up.

Why it happens and what we're after

Unstable braking: move brake bias forward, lower brake force a bit to reduce lock-ups and raise the rear coast lock to keep the rear in line.

What to change, exactly

Ranges, steps and defaults are the REAL ones for this sim. The amount is expressed in the game's own unit so you can apply it without converting anything.

  1. 1.Brake bias

    Raise ↑ by 2 %2 slider steps

    Range: 30 – 90 % · Default: 59 %

    Percentage of braking sent to the front axle. Forward (higher %) = stable, powerful braking; rearward (lower %) = helps brake-rotation and avoids front locking on loose. In rally, don't go too far rearward (rotation comes from the handbrake).

    What changes when you move it this way

    More forward: more stable braking, but more risk of locking the fronts and understeering.

  2. 2.Brake force

    Lower ↓ by 150 N·m150 slider steps

    Range: 1230 – 3690 N·m · Default: 2460 N·m

    Maximum braking torque available, in N·m. High = stronger, shorter braking, with more locking risk; low = more modulation and fewer lock-ups on low grip (gravel/snow).

    What changes when you move it this way

    Less force: more progressive feel, fewer lock-ups on loose surfaces.

  3. 3.Rear diff coast lock

    Raise ↑ by 4 %4 slider steps

    Range: 0 – 44 % · Default: 28 %

    How much the REAR diff locks off-throttle and braking (4WD/RWD only). High = a more stable rear on entry (prevents lift-off oversteer); low = more entry rotation.

    What changes when you move it this way

    Higher: more stable entry, stops the rear stepping out on lift/brake; some understeer.

    This adjustment does not apply to front-wheel-drive cars (the differential acts on the driven axle).

How to apply it without losing your afternoon

  1. 01Change ONE thing at a time and run three clean laps before judging. Two changes at once and you no longer know which one worked.
  2. 02Start with the first parameter on the list: they are in the order the engine applies them, from the one with most authority to the fine tuning.
  3. 03If the change goes the right way but falls short, repeat the same step again before touching another parameter.
  4. 04If it gets worse, put it back. A setup you don't understand is slower than a baseline you do.

Where this sim stores its setups

EA Sports WRC does NOT support importing/exporting or sharing setups by file in-game. Settings are saved inside the savegame per car and per surface/condition. To 'share' setups the community copies values by hand from external sites (e.g. WRCsetups.com). Local PC location: AppData\LocalLow\Codemasters\EA SPORTS WRC.

If that wasn't it

Symptoms get confused with each other: what feels like poor traction is very often oversteer on throttle. These are the other diagnoses for this sim.

The same problem in other sims

Same symptom, different parameters: each game exposes different sliders, with other units and other ranges.
