If I have a character with Bumpers attached, and I play Involuntary Promotion on a car in my KO area, does the returned character receive the Bumpers in time to prevent the damage counters from being moved?

The damage and upgrades are moved at the same time. Bumpers effect wont stop the damage counters from being moved.
