Well, I'm waiting until my driving force GT arrives, but I already did the bronze at Monza, with Dual Shock. If I run It again and finish with bronze again, will I earn the XP... again?
I think you meant Special Events, not Seasonal. In the current round of Seasonals, you can re-run them for more credits/xp.
In Special, if you've gotten bronze for one, then the only way to get more credits/xp is to then get silver or gold(preferrably!).
If you get a gold, then going back and re-running an event you won't gain any more credits or xp.
