Tuning Parameters

The tuning parameters table can be found in data/params.lua

You can add or remove just about any Handling value under #Parameters found here.

You should avoid allowing modification to fInitialDriveForce, fDriveInertia and fInitialDriveMaxFlatVel if you want engine building and tuning to be meaningful.

Avoid modifying stance parameters beyond setting the label.
