Can't help with some of that, but The auto and manual have different gear ratios, not just different axle ratios, and the auto may not handle a Z06 axle. Check out the chart in post #5 in the follwing thread, showing both gear and axle ratios for various combinations...

thanks but that did not answer my questions lol....

simply does the grand sport have the same rear as a z06? and is it a direct swap for a a6 vette like the z06 rear is?

i see alot of guys doing the z06 axles and diff in the a6 when they have a setup like built tranny,blower,cam,meth setups....

im asking because i run across the grandsport rears cheaper than a z06 rear..

Well, I keep up with most of this stuff and I don't think it has been absolutely established beyond a reasonable doubt yet. I may have missed something though.

Here's what I know, granted not much.
