Anyone know the stock gearing for the '04-'06 GTO? And also, what about the gearing on a c6 vette and Z06

Thanx fellas. Do you think its worth it to change my gearing to 3:42?

Nope! The 3.46 is comparible to the 3.42's.

Gearing for the GTO and C6 is attached. I highlighted the strong gearing in the M6 and the Autos for comparing purposes.
