What's this lever do?
Every setting in the upgrade & tune menu for Forza Horizon 6, what it changes in the car, which telemetry signal it leaves a fingerprint on, and what to reach for when the car does the wrong thing. Distilled from years of FH community knowledge and updated for FH6's caster sensitivity, fixed brake-bias slider, aero-balance slider, and narrower diff ranges.
By category
Diagnose by symptom →Front vs rear spring rate sets the corner-balance floor. Softer end is the one that loses grip.
Dampers control how fast the suspension moves. Bump = compression speed, rebound = extension speed.
The cheapest balance tweak. Stiffer ARB on an axle = less grip on that axle.
Lower = lower CoG = more grip. Too low = bottoming and broken suspension geometry.
How the tires sit relative to the road. Sets the contact patch under cornering, braking, and steering.
Sets the contact-patch shape and how grip loss feels (gradual vs sudden).
Controls how much the driven wheels lock together — at acceleration and on engine braking.
Front/rear power split for AWD cars. Higher = more rear bias = more RWD-like.
Brake bias balances lockup risk front vs rear. Pressure scales overall braking force.
Trades top speed for cornering grip. Effect scales with speed² — irrelevant in slow corners.
Picks the speeds at which each gear lives. Final drive scales everything together.
