FH6Tuning

Stop guessing at tune numbers. Enter your car's stats and get a complete setup: tires, gearing, springs, damping, aero and diff with the why behind each.

FH6 Tuning

Turn your car's stats into a complete, ready-to-enter tune. Tell it the basics: power, weight, front weight distribution, drivetrain, tire compound, and what you're building for, and it calculates every value the tune menu asks for: tire pressure, gearing, alignment, anti-roll bars, springs, ride height, damping, aero, and differential.

Why each number, not just the number

Every section explains the reasoning in plain language. Lower pressure grows the contact patch and adds grip. Negative camber keeps the tire flat when the body rolls. Ratios step geometrically so every shift lands back in the powerband. You finish a tune knowing more than when you started.

Built for the way you actually tune

Guided entry mode walks you through the in-game menu one value at a time, with a progress bar and a checkmark for each field, so nothing gets mistyped or skipped halfway through.

Tune for the event

Circuit, Touge, Drift, Drag, Rally, and Offroad each target different behavior: ride frequencies, rake, aero split, and diff lock all shift to match.

Imperial or metric

Switch units any time. Spring rates are converted to the numbers the game's metric slider actually accepts, not raw SI values, so a metric tune comes out right instead of ten times too soft.

No accounts, no backend

Everything is calculated on your device. No sign-up, no network calls, no tracking.

Formulas are based on well-known community tuning guides, credited in the app.
