Final drive
Use a balanced final drive and tune individual gears after testing.
Why: Final drive moves the whole gearbox shorter or longer.
Test: Change final drive first, then individual gears only if one part still feels wrong.

Gear Ratio Calculator
Tune final drive and gear spacing around the route, not just the biggest speed number. The output tells you what to test first.
Preset links keep the selected options in the URL. These outputs are baseline tuning notes, so test in-game before calling a setup final.
Generated baseline
Forza Horizon 6 gear ratio baseline
6-speed road gearing with balanced priority.
Gear spacing
Close the gap around the problem shift so RPM does not fall too far.
Why: Gear spacing controls whether the engine stays in its useful power band.
Test: Watch the RPM drop after each shift during the part of the event that matters most.
Launch test
Use first and second gear as the launch test before tuning top-end ratios.
Why: Many bad gear tunes start with fixing top speed before the car can launch cleanly.
Test: Launch three times from the same point and watch first-to-second behavior.
Top-speed test
If the car never reaches top gear, shorten the upper gears or reduce top-speed target.
Why: A useful top gear should be reachable on the intended route.
Test: Use the longest straight in your target event, not an unrealistic highway-only test.
