Thx mate but...I'm sorry I explained badly. I mean the improvements that can be made in the car. (upgrades.ini) I need to modify the .gen file or delete the .uno files where the upgrades are
You'll need to edit the Upgrades.ini file and remove what you don't want... But be careful. If there's any graphic upgrades, you'll need to edit the GEN file too and replace the upgrade parts, for example <LFWHEEL> with the GMT filename directly.
