This video of a 2011 135i/DCT certainly does not give the impression of a vehicle with excessive body lean.

I tried to get to the bottom of this in another thread. Truth be told, there are not enough people around here who have driven both the 2011 and earlier models and there are lots of HPDE types who will modify the suspension of a 2011 anyway, because no matter what the improvement, they want an all out track suspension.
