Chevrolet has made a number of refinements to the 5th Gen. Some are running manufacturing changes that you can see. i.e. more rubber in the sub-frame bushes. They have improved the damper map making it a bit more aggressive especially on the bound side. The relocation of the rear sway bar and a slight increase in diameter create a substantial change in sway bar bias. These and other changes do make the 12 a better car.
Having said that, an all out full build suspension on a 2010 compared to a full build all out out 2012 would be a virtual dead heat.
