Wow! That's alot of information that sounds great! I guess buying a 2007 z06 will not be so bad?

An 07 Z06 will be just fine. Ask me how I know. :thumbs:

\wow! that's good news! so in comparison to a 2008 z06 a 2007 z06 isn't bad performance wise?

The TR6060 is more robust compared to the T56. The synchronizer keys on the TR6060 have been re-designed for less effort. Everything inside the TR is bigger except for the synchros. I have personally drove both T56/TR6060 equiped vehicles and I do like the TR6060 better. Below are some comparison pictures.

The C6 Z06 diff does have carbon clutches, BTW. Look in my sig for comparison pictures (C5/C6 Z06 diff).

Old thread new info. Be advised that some 07 Z06s have the 6060. Mine, with a June 7 2007 in-service date, does. I’m guessing they switched the line over just prior to starting 08 production. Don’t go by year, always go by VIN.
