Alignment (Camber, Caster, Toe)
How the tires sit relative to the road. Sets the contact patch under cornering, braking, and steering.
What it does
Camber is the inward tilt of the tire as viewed from the front. Negative camber tips the top of the tire inward; as the car rolls in a corner, the outside tire flattens onto the road. A common starting point is −1.0 to −2.0° fronts, −0.5 to −1.5° rears. Too much and you wear the inside in straight-line driving (and lose braking grip).
Caster is only on the front: the tilt of the steering axis. Positive caster (almost always positive in Forza) increases self-centering and adds camber gain when steering — meaning more grip in slow corners without paying for it on the straights. FH6 is noticeably more sensitive to caster than older Horizon titles — values above ~6.0° feel snappy on turn-in. A safe FH6 range is 5.0–6.0°.
Toe is the angle of the tires viewed from above. Toe-in (toes pointing together) adds stability but hurts turn-in and adds drag. Toe-out adds turn-in response but makes the car twitchy. Most road/track tunes run zero or slight toe-in at the rear, slight toe-out at the front. FH6 sign convention is inverted from real-world: a NEGATIVE value is toe-in (stable), a POSITIVE value is toe-out (responsive) — so stabilizing rear toe-in is a negative number in-game.
In-game controls
Watch these telemetry signals
- Tire temperaturetireTempCWhere: Corner panels, tire temp heatmap (cold blue → optimal green → hot red)Forza gives one temp per tire (not 3-point). Asymmetric F vs R on the same side hints at camber bias; hot fronts + cold rears = front-end pushing.
- Tire slip angle (lateral)slipAngleWhere: Corner panels, "slip A" — compare front vs rearHigh slip with low temp on the same tire = that tire isn't loading evenly — usually too much camber for the speed range
- Steering inputsteerWhere: Trace strip, yellow lineConstant correction (steering trace dancing) at speed = too much front toe-out, or too little caster
Symptom → fix
| What you feel | Likely cause | Try this |
|---|---|---|
| Inside edge of front tires runs much hotter (relative to others) | Too much negative front camber for the cornering speed | Reduce front camber 0.3–0.5° |
| Outside edge runs hotter, car pushes mid-corner | Not enough negative camber — outside tire rolling onto its shoulder | Add 0.3–0.5° negative camber |
| Twitchy on straights at speed | Too much front toe-out OR (FH6) too much caster above 6° | Reduce front toe toward 0; if caster is already 6°+, drop it 0.5° rather than raising it |
| Car feels slow to turn but stable | Too much rear toe-in | Reduce rear toe toward 0 |
| Rear wags after gear shifts / throttle stabs | Rear toe at 0 with stiff suspension | Add −0.1 to −0.2° rear toe-in for stability (negative = toe-in in FH6) |
