I think the Camaro should adopt something sort of like the Nissans AWD platform, the thing is, it technically AWD until it needs to be.
PLEASE READ THIS, it is very informative and a very interesting system. (Primarily near the bottom) As for the DCT I still like it, but as for modifying, bleh, doesn't look fun to make it useful considerably above stock HP
