@ NukeStar:

You are mentioning a rule that I suspect to exist, too. I haven't enough data yet, but what I can say is that the drop rate of Electric Engines is definitely higher than that of High-Grade and Serial Racing Engines, for example. I think has to be regarded as a certain range of probability instead of a fixed value for all rare items.

And yes, the drop rates of blueprints are really funny. I'm still collecting data on this, but I agree on the Torq. I think that the drop rates given in the box info are correct in the long run, but that there are changing periods when certain blueprints are favoured.

Just have a look where the Marussia was in December and where it is in January. Or the Giulietta.
