Forza Horizon 6 Tuning Calculator

Live calc | Model last updated: July 18 2026 | rev·16

forza.tools is a free tuning calculator for Forza Horizon 6. Enter your car's power, weight, drivetrain, and build, and it generates a complete FH6 tune — tire pressures, gearing, alignment, anti-roll bars, springs, damping, aero, brakes, and differential — built from the consensus of seven community tuning guides and calibrated against the game's own performance stats.

Announcement
  • Jul 18 Accuracy wave: damping model corrected (the weight-shift term is gone), FWD and AWD differentials re-sourced, symptom-based balance nudges, Sport (final-drive-only) gearbox support, and realistic front-weight defaults.
  • Jun 11 New: seven per-discipline tuning guides — drift, drag, circuit, rally, off-road, touge, and top speed — explaining the why behind every number.

01Section

Tires

Pressure sets contact patch and temperature — the foundation every other FH6 setting builds on.

02Section

Gearing

Final drive and ratios decide acceleration vs top speed — matched to your power and goal.

03Section

Alignment

Camber, toe, and caster control how the tire meets the road through corners.

04Section

Antiroll Bars

ARBs balance body roll front to rear — the fastest way to fix understeer or oversteer.

05Section

Springs

Spring rates carry the car's weight — stiffer for response, softer for grip over bumps.

06Section

Ride Height

Lower centers of gravity corner flatter; rough surfaces need travel.

07Section

Damping

Rebound and bump shape how the springs move — the difference between planted and bouncy.

08Section

Aero

Downforce buys cornering grip at the cost of top speed.

09Section

Brakes

Bias and pressure decide how hard you can brake before lockup.

10Section

Differential

Diff lock controls how wheels share power — exit traction vs rotation.
