The complete car-tuning companion for Gran Turismo 7. Enter the handful of numbers you can read off any car, its weight, power, drivetrain and tyres, and copy back a full settings sheet that drops straight into the game's Fully Customisable parts. Your first car is free, and it is the full sheet: every tyre grade, every build, every track and the whole balance slider, copied out as often as you like. Unlock Pro once, with a single payment and no subscription, to tune your whole garage. EVERY SETTING, NOT JUST SPRINGS • Suspension: body height, natural frequency in Hz, anti-roll bars, compression and expansion damping • Alignment: negative camber and toe angle, in the game's In/Out convention • Differential: initial torque, acceleration and braking sensitivity per driven axle, plus the 4WD torque split • Brakes: front/rear balance matched to your weight distribution • Downforce: front and rear targets as a share of your car's slider range • Transmission: a top-speed slider target, plus the final-drive trick explained TUNED TO YOUR CAR, NOT A PRESET Five drivetrain layouts (FF, FR, MR, RR, 4WD), all nine tyre grades from Comfort Hard to Racing Soft, and six build types: race, road, sport, drift, drag and dirt. Every formula scales with your car's real weight, power and weight distribution, and every output already sits inside GT7's true slider ranges. DIAL IN THE BALANCE One slider moves the whole tune between stability and rotation. Springs, anti-roll bars, toe, differential, brake bias and downforce shift together, the way a race engineer would move them, not one slider at a time. YOUR GARAGE Save a tune for every car you run. Search it, duplicate it for a new build, and reload it on the grid before each race. KNOW WHY, NOT JUST WHAT The built-in guide explains what every GT7 setting actually does, in plain language, and gives step-by-step fixes for understeer and oversteer on corner entry, mid-corner and exit. It also covers ballast: where to place it and what it does to your weight distribution for PP and BoP targets. WHAT PRO UNLOCKS • Every car, not just your first one: a complete settings sheet for anything you drive • A Garage with no limit, so each car keeps its own tune • One payment, once. No subscription, no renewals, no account WORKS THE WAY YOU PLAY • No ads, and no account to create • Fully offline: tune in the lobby, on the grid, anywhere • Available in more than 30 languages • kg or lb, HP, PS or kW, km/h or mph, matching what your game displays GT7 Tuning Calculator is an independent companion app. It is not affiliated with, endorsed by, or sponsored by Polyphony Digital Inc. or Sony Interactive Entertainment.
