EA Sports WRC: car bottoming out — what to change

What it feels like

Over fast sections or compressions the floor hits the track, the car bounces and you lose grip exactly there.

Why it happens and what we're after

The car bounces / bottoms out: firm up fast bump so it doesn't hit the bump stop and raise ride height to give travel so the floor doesn't slam the terrain.

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.Front fast bump

    Raise ↑ by 2.04 slider steps

    Range: -5.0 – 5.0 · Default: 0.0

    Front high-speed compression factor (sharp impacts: bumps, rocks, kerbs). Soft (-) lets the wheel move up quickly on gravel; firm (+) controls impacts on tarmac.

    What changes when you move it this way

    Firmer (+): keeps it off the bump stops on big hits, but the wheel skips on gravel.

  2. 2.Rear fast bump

    Raise ↑ by 2.04 slider steps

    Range: -5.0 – 5.0 · Default: 0.0

    Rear high-speed compression factor (sharp rear impacts). Soft (-) lets the rear absorb bumps and keep traction on gravel.

    What changes when you move it this way

    Firmer (+): more impact control on tarmac, but the rear skips on gravel.

  3. 3.Front ride height

    Raise ↑ by 6 mm6 slider steps

    Range: 40 – 80 mm · Default: 60 mm

    ABSOLUTE front ride height, in mm (not an offset). Low = better stability and lower centre of gravity (tarmac); high = more suspension travel for rough terrain (gravel/snow).

    What changes when you move it this way

    Raising: more travel and avoids bottoming on rough stages, with more body roll.

  4. 4.Rear ride height

    Raise ↑ by 6 mm6 slider steps

    Range: 40 – 80 mm · Default: 60 mm

    ABSOLUTE rear ride height, in mm. The difference vs the front sets the 'rake': a slightly higher rear helps rotation and turn-in; lower stabilises at high speed.

    What changes when you move it this way

    Raising the rear: more rake and rotation, more travel over big bumps.

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.
