"Will this work if I have the car that rewards free upgrade. Upgrade (no pro kits) it and play mastery to get the free upgrade and use it on championship car. Then, I sync with local data. I guess, it will delete my upgrades on that car."


 * Yes (see if I understood your question), syncing your main device to the local data on the backup device will delete the max upgrades on the championship car... but only the ones applied after the previous syncing. So you might find it more convenient to max it to 5252 beforehand in case you (unlike me or Baabling above) are going for the car itself.

"But, will I keep the free upgrade for reuse?"
 * Definitely yes... just as long as you don't claim the rewarded upgrades on the backup device. (Well, it cannot be overstated that Cloud Swapping Tricknology is a dance that demands utter carefulness at each step...)
