Re: Getting Parts because of maxed Blueprints
Whenever you have all the blueprints for a specific car, the game gives only either uncommon or rare Street performance parts as rewards. You won't ever get any other performance part as one of the rewards in the events.
Off-Topic: When I won against Blake (I didn't lose the race to Blake), he said nothing on my screen as well.
I assume Blake's speechless after his big loss. 😛
