GT7 Tuning Calculator

Thank you for the feedback — this update rebuilds how tunes are calculated. • Spring settings now come as a slider position, not a fixed Hz number. GT7 gives every car its own Natural Frequency range, and a different one front and rear, so a figure like "2.50 Hz" lands somewhere different on every car. The position is the number that actually transfers. Enter your car's limits under Natural frequency range and the app shows the Hz that position works out to. • Your car now changes the tune. Weight and power reached almost nothing in the old suspension maths, so a light hatch and a heavy GT car could come out with identical springs, dampers and camber. They no longer do. • Anti-roll bars, differential, camber, toe and damping have been rebuilt around the baselines experienced GT7 tuners use, starting from your drivetrain rather than from spring rate. Rear toe-in in particular was several times higher than it should have been, which scrubbed speed on every straight. • New track type setting. Downforce now follows the circuit — Tsukuba and Le Mans want opposite wings — instead of being guessed from the build. • The Weight and Power fields can be cleared and retyped. Deleting the value no longer snaps it back to the lowest number, and clearing a field then changing your mind restores what was there. • Copy Tune and Save are no longer hidden behind the keyboard, and the Garage has a New Tune button so you can start a car from scratch instead of editing an existing one. Your saved Garage tunes carry over.
