Set the final drive so top gear tops out near the end of the longest straight, then tighten lower gears to stay in the power band.
This is a starting tune, not a guaranteed optimum. Forza Horizon 6 physics and your driving style matter, so test on track and adjust. Stiffen for grip and response, soften for stability and bumps.
Frequently asked
How accurate is the tuning calculator?
Spring rates are calculated from your car's weight using the standard natural-frequency model used across sim racing, so they are a strong baseline. Anti-roll bars, damping, alignment, pressure and the differential are proven community starting points by discipline and drivetrain. Treat the output as a fast starting tune and fine-tune to your car and style.
Where do I find my car's weight?
Open the car in the Upgrades and Tuning menu. The weight in pounds is shown with the car's stats, and it updates as you fit weight-reduction parts.
Why does front weight matter?
Spring rates scale with the weight each axle carries. A nose-heavy car needs stiffer front springs, so entering the correct front weight balance gives a more accurate result.
