I am also thinking of doing a Dynotech rear end change to the 3.90 with my 99 M6.
If that 3.90 rear gearing and T-56 trans gives you the same effect as a Z06 then that
should do the trick. Guess it would feel like the car has 100 more hp.
My Caddy CTS-V has the LS6 and the 3.73 rear end and its hard to hook with the smaller
245 wide tires, just shreads them, need to upgrade the rears to 275/35/18's in the spring.

I would like to put the cars head to head and see how they stack up.
