I think this too is a great idea! A handful of G8 owners have replaced their full diff assemblies with the Camaro ones (it fits apparently).

Having a GXP I already have a 3.70 rear-end but I wonder if the 3.91 would make a noticeable difference??? Anyone moved up .21 or so care to comment?

Also, why not go with the supposedly better 4.11 from Richmond instead of the 4.10?
