It seems like the first generation springs can be physically installed but they may provide a different drop than advertised since the 2010+ models are heavier. The suspensions are similar enough to use older model springs on your 2011 but I would be a bit concerned about the difference in weight between the cars, especially on softer, progressive rate springs like the progress springs.
They might work just fine but you'd have to buy them and see for yourself. It seems like not too many people have tried it yet.
