If you choose an Automatic Z51-equipped Stingray Coupe (1YX07), then it will automatically come with the 2.73 ltd slip rear instead of the 2.56 rear. Perhaps the Auto trany's close gear ratios does not necessitate the need for such a low (numerically high) rear axle ratio.

If you stay with a manual Stingray Coupe (whether 1YY07 or 1YZ07), they all come with the standard 3.42 ltd slip rear axle.

So far the order guide only lists these three rear ratios... I recommend to wait until you can test drive an Automatic Stingray, both with and w/o the Z51, before deciding to opt out from buying a C7.


Yes it is. Personally, I'd want a manual tranny C7 anyway...
that 7th gear is going to be a clunker... unless your on the freeway; in which case it should be amazing mpg's.


7spd all the way.
