Well the 2010 370/385/399 manual combo is factory rated at a 8.02 weight break and now with it at 399 hp its a 7.73 weight break which makes it a natural CC car so it could add weight and run A.

The 2010 392/375hp manual combo has a weight break of 8.53 for a natural B car.

And then the 2011 512/450hp manual combo is factored at 7.50 for a natural CC car which can add weight to run A.

I don't know how to drive an automatic so I'm looking at the stick combos since I would have built a stick CJ. To me it looks like they all could run A and the 392 can run A, B and C.
