Description
The complete car-tuning companion for Gran Turismo 7. Enter the handful of numbers you can read off any car — weight, power, drivetrain, tyres — and copy back a full settings sheet that drops straight into the game's Fully Customisable parts.
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
Ballast weight and position for PP and BoP targets
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.
WORKS THE WAY YOU PLAY
One price, everything included — no subscription, no ads, no account
Fully offline: tune in the lobby, on the grid, anywhere
Available in 38 languages
