Default Grand sport diff into 07 base?
What is needed to put a grand sport auto diff into an auto 07? I've been told the gs diff is the same as the c6z but did it come with the cooler as well in the automatic?

now that I've researched it some more I think the gs a6 diff is the same as the base diff. It seems to be the m6 that got the better diff in the gs model.
