Indeed this has been confirmed:

''Your points will get reset if you reverse your upgrades by cloud restoring or side loading a save game, or if you buy a car and then cloud restore to get your gold back. These things are considered exploiting the game.

''Time trial times get reset if the affected car is used in that time trial. OMP is a bit different due to the way the car schedule is stored. If you do this to any car your OMP rating will get reset.
