It's just wheel hop, the car is trying to spin your tires but not quite powerful enough. My last car did the same thing and my 535 does it too.
As Stuck mentioned above, a lot of things contribute to it, but the smallest cracks or bumps in the road will cause this. Make sure your DSC is completely off as well, hold the button down for 5 seconds to turn it completely off.
