The following exploit forces you to mess with computer files and in-game files. Because of this, attempt the following at your own risk.

Head to your Pure installation folder and find the path entitled Data-Vehicles-Handling-Tuning. Open up the DefaultTuning.params file in Notepad, which will allow you to change the values (make a backup of this file in case you mess it up and want to replace it!) Modify the numbers found near StatModifier and StatBase (the numbers appearing in parenthesis represent the set values). Set them to their maximum value, and head back to the game to take advantage of your new-found exploit!
