REAL RACING 3 F1/FE/GTE/NASCAR DRIVERS AND TEAMS PRINCIPAL HACK
Current version: 18.104.22.168.5
Working RR3: 9.8.4
Run this script to get the maximum levels of drivers and teams principals. You still need gold and m$ to level up, but no points.
Run the script wherever you want and then update your drivers and teams. You need at least one point if you want your upgrades to be permanent. Otherwise, select the appropriate entry when you run the script.
THANKS TO @impy !!!
