Changing the ring and pinion going to create drama?

Thank you for the update on what can now be called, "mission impossible". Well that's unfortunate, seems GM sorta shot themselves in the foot on giving customers the option to easily change their gearing preference.

Thank you for all of your help, I am now off to tell my friend it's v-8 time...no offense to the v-6 crowd out there, Formula 1 engines are pushing a 1000 hp.
