GT7 Tuning Calculator v3.1 Lite only(mobile and Web friendly) NEW CARS ADDED!

GT7 Tuning Calculator Lite Version (can be used with excel online or a mobile device) has been built from years of real life and sim racing experience, I have been obsessed with Gran Turismo since the early days, while also building my own turbo charged race cars in my friends workshop. After GT5 went offline I moved over to iRacing for a time. Until last year when I decided to rejoin the Gran Turismo racing sim world! So here we have my suspension calculator along with a gear ratio calculator to help everyone make the most out of this complicated yet exciting game!

All updates to the calculator are included in your purchase.

if you have any questions or feature request please feel free to message me through this website or via GTPlanet, username hookedonturbo.

Safe racing hopefully see you out on the track!
